I liked what dan_d_builder (thanks for the design Dan) did with replacing the joypad for the Amiga CD32. However, I thought it could go one step further and improve a bit on the stock design.
So I came up with three "improvement" designs.
Pick the one you like and print.
Mine were printed with PLA at 20% infill 0.2mm and came out well. I also made a half dome 6mm width which you can print two of and stick together, to stick on the underside of the joypad prints. I did not test the half dome yet but it should work fine.
Obviously with a bit of cleaning, you should get pretty good results.
I have more ideas for designs (like a mini joystick) but thought some might find that idea odd, so I thought I would start with these 3 for now and see if there is more interest.
I created them using Tinkercad, so I could share them if required.
Unlike some, I quite like the CD32 joypad. :)
