That is so awesome, thanks for sharing and glad you put this to use!! Happy making!

Thanks for the love! I broke it down for 15 pts per drawing (original & redesigned), 25 points per model (original & redesigned) and 20 for the presentation making it 100 pts total. For scoring, I graded based on guidelines set, such as including labeles on the blueprints, color coding them, including a certain number of features in the models, etc. I did not grade based on quality as all of my students were really demonstrating a huge variety of skills and prior experiences. Instread, it was on the design process of completing the challenge.

Thanks for the suggesiton and love! Modeling out of clay may save time for you, but I assure you that my thumbs do well with digital modeling and would make an absoleut mess with clay :)

Truly beautifu work, thank you for sharing!

Happy to help! And yes, that's kind of what I meant. If you were going to make a lot of the same pattern, you could cut out the inverse to hold things in place and assist in perfect alignment. Keep me posted with your creations, can't wait to see what you come up with!

Thanks for the love! In theory, you could totally print on the substrate before cutting, but as you mentioned there is a chance of soot residue discoloring the image. The unisub hardboard I used in this tutorial burns A LOT, I would definitely look into using a wood, faux wood, or plastic coated for dye sub instead. Alternatively, you could create yourself a jig to make it easy to align your image, in combination with some bleed in your design I think it would work well. Hope this helps!

This is so awesome and creative, well done and thanks for sharing!

Awesome first instructable!

I saw this, such an awesome instructable! I really liked the simplicity of your filament change with alternating layer heights to do two filaments on a single print head. I also really appreciate your explainations while testing the conductive PLA's resistance. Thanks for sharing!

Thanks for the love!

I agree! I've seen really awesome dual material prints that actually 3D print components, as well as the PCB. Awesome examples and thanks for sharing!

That's a really cool idea! I personally haven't tried using PVA for anything other than dissolvable supports, but a disolving PCB is a pretty intersting idea. Thanks for sharing!

Thank you and will do!

Many thanks!

This is really awesome, you seem like an phenomenal teacher (assuming that's what you do?) and an above and beyond first instructable! Well done!!

Many thanks!

Nice work!

Thanks!

Such an awesome suggestion, thanks for sharing!

Many thanks!!

This is so cool, thanks for sharing!! I have always been mesmerized by laser cut maps and cityscapes. Nice work!

I feel like my life is complete now, thank you

This is so clean and beautifully made, thanks fro sharing!

Awesome job and nice use in combining two programs! Thanks for sharing! I would add the year to the back or the corner.....but that's just me and my memory :)

Awesome job and thanks for sharing! Good luck in the contest!

This is truly awesome, and I'm inspired. Thank you for sharing!

This is so beautifully made, thank you for sharing!

This is really awesome, but as many mentioned I'd fear from toxic off-gas in the material. While it's not as cool, you could make fake records from black acrylic with the same idea as this is such an awesome project! Thanks for sharing, be safe!

Thanks for the support and feedback!

No problem! I'll send the files your way! The only constraints with AI is that the artboard has to be the same size as the laser bed, red / blue strokes have to be pure CMYK codes and same with black fills for engraving. Lastly, all stroke weights have to be 0.001pt. We haven't be able to successfully sent stroke weights for exporting from onshape, so that's a post processing step in either gravit designer or AI.

Thank you, truly appreciate your feedback and suggestions! I do use this lesson as an opportunity to discuss and teach the metric system and talk about how / why the US is one of the few countries that still use the imperial system. I do what I can, one small class in New Jersey at a time :)

Thank you!

Thanks for the love, truly appreciated!

Thanks for sharing and for the feedback, truly appreciated! Glad I could provide some support and things for you to use as well!

You know, technically none of the above. It is based on an OLD banana bread recipe though, thus the name. Thanks for reading!

Completely with you, using wire strippers with younger students can be really challenging and difficult to teach. We use automatic "alligator" like wire strippers in our K-5 makerspaces (below) Knoweasy Automatic Wire Stripper and Cutter,Heavy Duty Wire Stripping Tool 2 in 1 for Electronic and Automotive RepairAnd a combination of self-adjusting wire strippers and classic snips in 6-12.

Inkscape is another great option! I've had issues with inkscape on chromebooks though as it requires a secondary app that is blocked by my school district. But on a personal device, its an awesome free alternative. thanks for sharing!

thanks!

It does! That wasn't the intent of this project as these were "permanent" chalkboard signs for aesthetics, but the paint is pretty cool for making your own. I would just do at least two coats if you planned on writing on it and washing it off regularly.

thanks!!

thank you!

I've only tried it with puree which has a really similar consistency as mashed up bananas, but I would think pie filling would work too. It may just have a different texture.

This is such an awesome tip and trick, thanks for sharing!

As a teacher, we still call whiteboards blackboards or chalkboards so I completely hear you. But as you mentioned, chalkboard signs are now being used as decorative pieces all over the place. From my searching, they usually cost a small fortune.....hopefully this Instructable helps those interested in making their own "permanent" chalkboard decorative signs. Thanks for sharing!

I used the paint mainly for permanent / decorative chalkboard signs as demonstrated in the Instructable, but it absolutely works to make chalk boards. I found that more coats really is helpful to make a usable chalkboard, I would do 3 or 4 personally.

Great question! I use a variety of tools depending on the age and situation. For our K-5 makerspaces, we use the following Automatic self-adjusting strippers that you load from the front. We call them "Alligator" strippers, the blade is hidden and super easy to use. They just aren't great for really thin stranded wire. See below. https://www.amazon.com/dp/B013NZK87I/ref=sspa_dk_d...We also use the following "snips" for thin wire and general cutting, as well as cutting other things like skewers with ease. https://www.amazon.com/Cablelera-Stripper-Cutter-1...In my 6-8 space, and in our high school, we go back and forth between the following self-adjusting and typical strippers.https://www.amazon.com/IRWIN-VISE-GRIP-2078300-Sel...https://www.amazon.com/Stripper-Cutter-10-…

They are difficult to use in tight spaces or with really thin wires, so that's when we throw in the two typical strippers. Hope this helps! Happy making!

Hey thanks! I couldn’t resist

Thanks!

This is pretty cool and I plan to make one for my classroom, not for the machines though. Probably to turn my stereo on or off. Thanks for sharing!
