Tinkercad actually has feature that allows export to Fusion 360. You can access this feature by clicking the "send to" button on the top right and selecting Fusion 360. Sometimes this is a bit glitchy, but generally the conversion process creates decent results.You can then export .step or .f3d files through Fusion 360.

I'm sorry that you had to go through so much troubleshooting to get the electronics to work. I will update the build instructions according to the list, and I once again apologize for all the problems.Thank you so much for taking the time to troubleshoot and to report the issues back to me, and as always, if you encounter any problems in the mechanical setup, feel free to let me know.

I'm glad that you're asking those questions! They help me fix the problems that may arise so that more people can build it without problems.In my experience, decimal numbers work just fine, and I recommend uploading an I2C scanner to the arduino nano to check the address of the ATiny85 (https://playground.arduino.cc/Main/I2cScanner/)Make sure that the programming jumpers for the ATTiny are disconnected or otherwise I2C will not work. If the ATTiny is able to be detected at address 9, reupload the code and try disconnecting the OLED screen and see if that helps. Sometimes bad OLED screens can lead to I2C problems.

Great! I will update the code accordingly. Please let me know if you have run into any further problems. I will be glad to answer them.I think I used the 8mhz internal clock for the ATTiny85.
View Instructable »Strangely enough my TinyWireS library does have uint8_t receive() but it is in the place of uint8_t read().You might be using a newer version of TinyWireS while for some reason I have an older version. Try changing receive() to read() in the ATTiny code and let me know the results.I will update the instructions accordingly if needed.Thanks.

Hello,I am unable to reproduce the error on my setup using the same code.The problem might be in your board or TinyWireS library. Similar problems have been reported on internet forums about the request() command. Based on the solutions on the internet, I recommend trying the following:1. Make sure you have ATTinyCore board library for the ATTiny85. Even though it's unlikely that bad board libraries can mess up this stuff, it's always good to make sure.2. Download and extract the TinyWireS library straight into the folder where your sketch is located and see if that helps. (solution based on https://arduino.stackexchange.com/questions/9244/i%C2%B2c-between-attiny85-8mhz-and-arduino-uno)If the above two don't work, try and compile the examples given in the library and see what happens.Plea…

I'm glad that you're interested in building this! Sorry for not replying to this earlier. Instructables didn't notify me on email :(The maximum force limit is not known, but I recommend staying within 2kN, exceeding that number may cause the coupler to slip.As for the lead screw pitch, you may use a lower pitch lead screw but make sure to choose a stepper motor gear ratio accordingly as well because the stepper motor will need to spin faster in order to reach the desired linear movement. This means that for a 4mm lead, I recommend gear ratios of less than 50:1.You may choose the model of load cell to use, so technically speaking there is no fixed load cell limit.

Hi, I'm so glad that you made the machine! Though a new version is released with better grip systems https://www.instructables.com/Universal-Tensile-Te... consider upgrading to the new version if you need better grip on the specimens or more features (the electronics can stay the same).As for the unknown command, the Arduino serial monitor automatically adds a "\n" to the end of the line, causing the error. You need to change the prompt in the screenshot to the equivalent of "no line ending".

- CrazyBlackStone commented on 1526379's instructable The BEST Potato Masher -TinkercadView Instructable »
Great idea! I like the design of this.However a warning needs to be mentioned on how this is going to be printed. To put it simply, the FDM 3D printing process is NOT food safe. The extruder gear and the nozzle are often made of brass, and this means that there is a possibility that the print can be contaminated with lead, which is sometimes found in brass. Also, although PLA is food safe, the pigments that filament manufacturers use might not be.
- CrazyBlackStone commented on Nikolaos Babetas's instructable Automatic Hand Sanitizer DispenserView Instructable »
I know that this is 19 days ago. But since you're using a DRV8825 to drive the stepper motor, have you tried to simply reduce the delay between the pulses? I see that the pulses have a length of 2000 microseconds, so maybe you can reduce that to 500 microseconds. This should increase the number of steps driven in a certain amount of time and therefore result in a faster speed.At this kind of speed and application, the stepper motor size and torque rating should not matter very much, if at all.

Silly me messed up the wording for "door handles" and referred to them all by "doorknobs". Like mentioned in step 23, round door knobs cannot be turned by this device.I also demonstrated the device using a regular door with a handle in step 23.
View Instructable »Took me around 10 minutes to make this. I didn't bother making an instructable for it so here they are. I'm not sure if they would work. The idea is that the two parts will be clamped together using M5 bolts, and these bolts directly screw into the plastic of the back plate.

Haha, you are absolutely right, the value is in the experience.Also it turns out that I did not know the concept of the difference between door knobs and handles :/, so thanks for indirectly helping me in realizing something I should've known a long time ago.

I totally agree. There's a lot of things you don't get right in the first iteration. I have experienced this in many ways, and this project is no exception.The version I'm presenting here is actually the third version. The previous two versions were not shown in this instructable but had several issues that were fixed in the end.
Thank you so much for your kind words!

This reminds me of the croissant sandwich that my mom and I had "invented". We started off with tuna, cheese, and butter, which was strange but tasted quite good.Later on we tried different styles, and one of those was actually Italian ham and cheese. It's quite similar to yours and tasted amazing.Also, we used an air fryer to toast the croissants and that made it super crispy.

I made my homepage image by first rendering with Fusion 360, and then I used paint.net to add the text. As for why the image does not appear in the actual instructable, it's because I originally put that image as the introduction image and also selected it as the title image, but then I went back to the introduction and replaced that image with the picture that you see now.For animations, unfortunately, I don't think that this instructable is the most appropriate place for explaining how to make an animation. But the assembly animation is actually included in the .f3d file, so you can download it, navigate to the animation workspace, and take a look.Attached is the animation timeline.

- CrazyBlackStone commented on Designingpro's instructable Hand's Free Door Opener: a Covid-19 Solution
For the most part, it's a yes, I like how you presented the different designs and even had a step detailed to how to print this thing. If any improvements can be made, I would say that adding a step (with picture) elaborating on how one would assemble the tool would add some extra awesomeness to this project.Also, For your third design, you can consider adding a chamfer/triangle down at the bottom of the outer overhanging edges. This is because FDM 3D printers can't print in mid-air without supports, and what you have there is a 90 degree overhang, which will result in a messy blob of "spaghetti" if someone tries to print that part without supports.
View Instructable »Yes.As for the animation, I made it in Fusion 360. You first need to download Fusion 360. Then you can send the design to Fusion 360 and make the bodies into components. Next navigate to the animation workspace and start making the animation. It's hard to explain exactly what to do, and this requires some quite a bit of if you've never used Fusion 360.I think the best thing to do for making assembly instructions if you don't have Fusion 360 is to make multiple pictures in Tinkercad on how the assembly would look.

Thanks for the comment and the suggestion. Though I think the idea of "hands free" is only relative. I can even argue that touchless sensors are not hand-free because you need to put your hand in front of them. The goal of being "hands free" is to avoid contamination by touching, and this device helps your hands to not come into contact with the potentially contaminated surface, hence "hands free". In my opinion, the method of evaluation for these tools should mostly come down to the effectiveness of the product rather than the etymology of its name. (a lot of other entries to the same contest are forms of door openers and/or hand-operated tools as well)

Hi,I don't quite understand what exactly you're mentioning, but this machine is completely original in terms of design and most of the principle of operation.If you're saying that Lulzbot has made 3D printers using 3D printed parts:Unfortunately, this is not a 3d printer, and I'm sure there are many good 3D printers out there that use 3D printed parts also. I'm sure rigid 3D printed parts are strong enough to be used for 3D printers, but that's not what this machine is made to test.I am not aware of anything made by Lulzbot that has a similar structure to my design, and the only thing I can find is where they built a small test jig using wood, some straps, and a crane scale. This is one of the ways you can build a low-cost tensile testing machine, but by no means is it similar to my desig…

Wow! This is such an amazing project!I am currently working on a large custom CoreXY 3D printer and an universal testing machine using Fusion 360 (it used to be Tinkercad), both involving stepper motors, and I'm just so impressed with how you managed to create this machine with the limited supplies you started off with. I think that, with the cost in mind, what you've accomplished was great.Suggestions:It seems like the stepper motor (or is that a brushless motor, can't tell) driving the Y axis might be skipping steps in the video. I'm not sure if the choppy movement is meant to happen, but if it is skipping steps, you might want to consider adding gears to multiply the torque.Also hot glue doesn't seem like the best way to mount things. The best way is to use bolts, obviously. I use M3 b…

Hi, thanks for the reply.PLX-DAQ data acquisition seems pretty interesting. When I used this machine for science fair last year, I just copied the data over to Excel by doing Ctrl+A and Ctrl+C quickly. But this seems like a more efficient way, so I'll look into it.Data analysis is a topic I've been thinking about. The traditional extensometers, being multiple times more expensive than the machine itself, are simply too expensive. I'm thinking about either using a digital caliper with digital readout for extensometer. It obviously wouldn't have nearly enough resolution, but it may just get by in the applications this machine is used in. PLX-DAQ would obviously help a lot when another variable, the extensometer, is attached.Unfortunately, this machine does not handle compression because the…

Thanks for bringing this to my attention!A little bit of flex is unavoidable with 3D printed parts like this; however, the PLA printed parts are surprisingly resistant to flex, and are even better if you print them with the maximum number of shells and 100% infill.I have performed an analysis in fusion 360 with a the stationary grip designed for the Thingiverse release (which is very similar to the Tinkercad version and should work the same way). The material is set to PC-ABS, which actually has a modulus of 2.78 GPa, less than the 3.5 GPa specified in the datasheet for the recommended PLA filament. A maximum displacement of 0.04704mm was observed in the X direction near the top, which is, to me, very little. And a safety factor of 15 is observed on the entire part. Though I'm no expert o…

Hi, after doing a little bit of digging, I agree with you. Bolt-down chassis mount commercial fuse holders do often use nickle/zinc plated steel for the contacts and those are often rated for quite a high current (100A), and plus those puny little glass fuses can't take more than 20A anyways. Smaller PCB mount fuse holders all use brass or tinned copper because they need to get the resistance low in a small amount of space. I did the resistance calculations and it seems that the resistance for a 2d size nail cut to 12mm length is only around 0.11306milliohm, so it'd be more than well within the resistance limit for this application.I think you did an amazing job on this project and I hope that you win first place in connectors :)

Unfortunately the global semiconductor shortage we are in right now pretty much made genuine STM32 chips impossible to obtain without paying a lot.I would assume that clones like GD32 or CS32 might work as substitutes for the microcontroller while we wait this out.
