HI guysSo I was helping out with a junior high project where the students got to 3d print their own phone cases. We had them use tinkercad to import phone cases, then they got to edit them via tinkercad. Real simple, but the kids loved it! Either way I couldn't find a good phone case model out there so I sat down and made one for them. It's blank so you can personalize it yourself! Have fun!It was designed with a 0.4 mm diameter nozzle in mind, so the wall thicknesses are multiples of 0.04 mm. It should be easy to print.A couple of different files are avaliable, two stl's and one .123dx file. 123d design is an autodesk product, it's like a simplified cad program, and once again is free and school friendly just like tinkercad. If you plan on using this in a classroom like me the workflow goes like  this:1. Find a "3d printable" case for your phone.2. Upload the stl file to tinkercad. 3. Create or upload assets to attach or cut out of your case.3. Download the stl of your case. 4. 3d print! If you use this or make other projects via this case I would appreciate a shout out to the work I have done, I thrive off of feedback! (seriously it gives me superpowers)
