This is a remix of jtritell's Atari 2600 Paddle Controller Replacement Wheel.

I found his STL to be a little blocky on the rounded surfaces, so I increased the mesh count to make it smoother.

Also, and more importantly, I modified the size of the half-circle hole that the controller knob inserts into. I found that the original file had this hole way too big...or maybe it was just right if you had the original metal spring clip still on your controller. If you don't have this spring clip (like me) then this hole is too big, so I've made the hole smaller to get a good friction fit onto the knob.

The original controller wheel would have a chamfered edge on all the ribs at the top, but I left it flat so that it prints better. If you'd like a chamfered edge file, just send me a message and I'll add another model option with this feature.
