I have an old Devastator II controller that I am using for MAME. I have created a template in CAD (see attached image) that I would like to print out on a stiff plastic that I can use as an overlay for specific games (to stay loose - held on by the 6 bottons, not stuck on) . I would like it to stay somewhat stiff to help keep it in place, so I imagine the plastic would need to be about 1mm thick. Another idea is to print it out on vynil, but I am a little worried about the life of it being so flimsy, and to ability to store them without hassle.
Do you guys have any suggestions at where to get these made? Or have alternate ideas on how I should/can approach this idea? It seems like this may have already been done by someone else before, but I can not find any examples through Google.
