The Atari 2600 was my first games machine and so the CX40 was my first joystick and it survived long enough to be used with my ZX Spectrum and C64. I loved that hunk of plastic but I knew even then that it wasn't the best joystick out there, so after 40 years and the purchase of a 3D printer, here is my remake of the CX40 with whatever quality level of arcade parts you want to house in it.

I admit, I have a cheap sanwa clone joystick installed and it feels good to me. Maybe it's the rose tinted nostalgia glasses blinding my view but I hope it brings a smile to some other players out there. Now you will have to excuse me as I have this strong desire to play some Battlezone, Empire Strikes back & Wizard of Wor on the old 2600 pixel pusher...

_4410H means: 4 top layers, 4 bottom layers, 10% infill and H is Hex infill.
_445L means: 4 top layers, 4 bottom layers, 5% infill and L is Line infill.
_Mrd means: Mirrored, if you prefer the fire button to be on the right hand side.

Update (31/03/2022): Added a cover update incase your joystick stem screw scrapes on the cover also another stick size variant - fits tightly.

Joy_cx40_cvr_v24_4410H - now has a circular indent to stop screw scrape.
Joy_cx40_cvr_v24_Mrd_4410H - mirrored version of above.
JST_cx40_stick_ALT2_4410H - If stem shaft is 33.5 x 8.7mm (not inc. screw top)

Update (25/03/2022):
I noticed putting one together that not all Sanwa joystick clones are built to the same specs so I uploaded an alternate stick to help with the issue.

JST_cx40_stick_v19_4415H - If stem/shaft is 37 x 9mm (not inc. screw top)
JST_cx40_stick_ALT_4415H - If stem/shaft is 35 x 8.8mm (not inc. screw top)
