Varies PLAVaries How I Designed This ===================
Designing:
I measured a challenge coin and modeled it in Blender. Then, I built the walls and added the tab that prevents the coin from falling out. Finally, I incorporated the cut design. There was a lot of trial and error involved, and I figured out along the way that a second tab was pretty important.
I used the percentage difference calculator () to make both sizes identical in function, just bigger and obviously a calculator.Software:
I used Blender and the CAD Sketcher add-on. Additionally, I used "https://imagy.app/resize-image-to-500kb" to get the images to the size required for uploading.
