I made a macropad which makes it easier to CAD by having dedicated shortcuts for copy, paste, and undo! I'm proud of being able to create this with very limited hardware experience, and also being able to use my CAD knowledge in conjunction with it. A challenge was creating the CAD in Onshape, since I didn't have space for Fusion on my PC. The CAD can be checked out on the public Onshape, and the Github has all the associated code!
