The joysticks I got for my arcade cabinet (http://www.arcadewinkel.nl/joysticks/balltop-arcadefighter-stick-rood) were fine, but I wasn't entirely happy with the restrictor plates that came with it. They worked fine in 4-way mode, but the 8-way mode was simply a square and that doesn't work nicely in most circumstances.

So I was looking around for replacement plates (preferably ones with octagons or maybe even smarter restriction holes), but couldn't really find any. And then I realized I have an f'in 3d-printer.

So I took out one of the existing plates, measured it, and fired up openscad to create new ones.

I'm starting to worry, I may run out of things to tweak on my cabinet soonish. Then what will I do with it.
