Modifying STL's

I am looking for a cheap, preferably free, program or suggested work flow to make changes or additions to a STL. The particular interest right now is a small mouse that I download from Thingiverse that I'd like to add a block letter to. Something I'm trying to do for an event at my dog club. I want to print it in green with a block "Q" on its rump. I have windows 7 and 8.1 along with Linux Mint and will soon have an Afinia printer. Thanks in advance for any pointers, Curt

VECTOR then To STL. Then to model

Behind on a project. Loooking for someone expireinced to turn a photo into a STL. File for 3D model. three sizes 2.5" , 1.5" and .75" Seems simple and straightforward but you'll have to see the image DUSTY dustflame415@gmail.com

Trouble with .stl sizing

I'm having trouble with the sizing of the .stl file model. In blender it says that I have everything correct and I've made sure that the scaling was applied but every time I upload it it says that its wicked tiny. I was hoping someone could give me suggestions on how to fix this problem or at least think of something that I haven't thought of yet..

Converting a .dwg into a .stl for 3D printing a house design (Converting to watertight mesh/ 3d volume)

Hey you guys,I am hoping to use the powers of a crowd to find a quick answer to my problem. I have the architectural Design (.dwg) of a given house (simple model for comparison attached). I need to convert this into a .stl file, preferrably using Fusion360 or Autocad. (newest Version)I understand that the type of the walls and roof is not a 3D volumetric type or a watertight mesh, so the question is how to get there. (Also: of what type of "structure" are these walls - I mean .. they are 3D?)I am an electronics engineer by training, so my CAD knowledge is rather restricted to PCB design. I would be pleased if you can help me out with this, so I can get back to those PCB's :)Thank you guys a lot!lusch

Chopping Up an stl file into multiples

Hi Everyone, I'm looking for some software help.  I have a single stl file of a Johnny 5 robot.  I don't want to print it all in one part. What I'd like to do is chop the arms, head, and other random parts off, and save them as separate stl files so the robot can be re-assembled. Ideally the chopped off arms would have male-female connectors to fit back into the body they were removed from. I'm looking for input as to what would be the best method to accomplish this both in software and technique. Any ideas would be appreciated.

modéle 3d

Bonjour, j'habite le nord de la france , je suis très intéressé par les nouvelles technologies , je me débrouille comme un débutant avec les logiciel 3 D ( rhinoceros sketchup ) j'ai un modéle de voiture 3D obtenu sur le net , que je voudrais transformer pour le rendre étanche solide stl pour pouvoir travailler dessus avec le logiciel 123D MAKE de solidwork et éventuellement l'imprimer ; qui peut le faire ou me guider pas à pas ,se serait cool ,

I want to print some gears, but I dont know how to make them

So I'd really like to make some geared mechanisms to be printed out, but the math is a little bit beyond me. Right now I have 123D and it does not have a gear generator. I was thinking that somewhere there has to exist a catalog or database of pre-designed gear stl files. I was hoping that somebody here might know of such a thing, or perhaps another way to easily make gears? I've been seeing all kinds of crazy gears made into really exotic shapes, but I don't know how these are made either. I'm assuming that the people that designed them are super geniuses, or that they have some kind of advanced software. Which is it?

3D printed combination lock anyone?

I am in the finnishing stages for a fully 3D printed dial combination lock, similar to what would be used on a safe.Unlike what you might find in other places there is no metal parts.No crappy amount of possible combinations either, 72 per dial dial...I took me a few weeks and quite some filament to get from a draft in Sketchup to something that actually works as planned.As it was more a training excersize in Sketchup for me I had the the following goals:1. Everything is 3D printed with as little afterwork as possible.2. All required springs are 3D printed as well as all other moving or stationary parts.3. Where otherwise fasteners or screws would be required only short leftovers of filament are used to keep the parts in place.Only exception for security reason is the mounts for the front dial and holder.These should be glued or screwed in place if the actual intention is to use it as a working lock.4. The lock shall not be pickable by means of felling, hearing or just trying out random combinations.The above points I got sorted to my satisfaction.However I would like some feedback from trustworth beta testers on the general design and functionality.It is one thing to design something that just works but a bit harder to design it the best possible way.Another big drawback currently is that it seems to be impossible to export proper STL files in Sketchup once they reach a certain complexity.Automatic services or programs to fix these issues result in drastically increased file sizes.Some of the problematic part go from just under 200kb to over 10mb after "fixed".This is not acceptable for me and I have to work on fixing this issue.Most slicers correct these tiny errors automatically and produce a correct print but I prefer proper STL files of small size and complexity over inflated ones that I then need to double check for a long anyways.A few details need changing as my tests showed that you can't drive up print details to a certain level without risking to be unable to mount the parts without further sanding.I hope to have a full set of clean STL files ready for testing by the end of this month.If you are interested to try it out and maybe contribute to an improved version your time will be valued by being mentioned as a beta tester for the upcoming Instructable.Be warned though!This is not for the faint of heart and certainly not for someone who does not know how to calibrate all aspects of the 3D printer involved.The lock also uses quite a bit of filament, currently around 37m all up but I am working on reducing this by replacing solid parts with framework instead where possible.The assembly can be time consuming and frustrating if you realise only once finnished that you have certain parts in the wrong position or orientation.But as said, my goals were not really on making it as easy as possible LOLWhy desing a lock that is neither secure enough nor free of metal parts if there is other options ;)If you happen to work with an Inventor and PLA on the left side then I can provide ready to go .gx files if prefered.They would then be already confirmed to be working and usable on one of my printers.Let me know what you think ...

Using Autodesk Fusion 360 or other package to make Lids and other form fitting parts?

First off, thanks for all the great posts and Instructables, I hope to be able to add to the growing collection sometime soon with a few projects I need to document.   Recently I have been trying to figure out a good way to create form fitting shapes with decent tolerances for  PLA printing.  I am using Autodesk Fusion and Blender using Boolean CGI operations, specifically the  Cut / Difference option. to create a appropriate sized cap.  If you have a peek at the attached image, the top part (red)  was used as a tool to cut out a matching body from a smaller cylinder (blue).  In the real world If these are printed, the shape would never fit together and if you did, you could never remove them.   What I would like to do is alter the bottom half to shrink it's surfaces inward about 0.25mm to allow for the expanding of materials. Every time I've inquired about this on some other forums, the first response Is  'Just use resize' and make the bottom half larger.'  Great idea, but there are a problems.  The inner plate/cylinder and radius walls expand to be too large The height changes, leaving a gap between the two surfaces Any suggestions would be great. I believe there is a path using Differences / Intersect and subtracting that, but I've been failing to find a solution to it.  I have included the Example top as an STL file.  Thanks for any suggestions.  And No this is not for a school project. Just a hobbyist looking to understand CAD.
