Biodegradable Keycap

This is my design for a keycap. I specifically wanted to make one, as through 3d printing, we have the opportunity to make it biodegradable.

Need access to Autodesk Fusion as well as access to 3d printer.

Sketch a square shape of dimensions of 17 cm. Extrude it up to 9.68cm

Create offset planes and make the sides of the structure fit into your desired angles. I used 80 degrees. make sure to mirror the same towards the other side.

Fillet the top edges and make the inside a shell with width 1 cm.

Start by making an offset plane and then sketch a circle of radius 2.75 cm. Then make this hollow + sign. Make sure to constrain these lines when doing so. Each line should have a maximum length of 1.26. Now finish the sketch and extrude it up towards 5 cm.

If You want to include initials, make a sketch on the top surface and add a textbox. Type down ur initials in your desired font and finish sketch. Extrude it to a negative distance, but don't make it cut into back of the keycap. Desirably extrude to a negative distance of .5 or below.
