Summary

My take on an Atari 2600/8-Bit CX40 coupler. Coupler is inspired by the blow-molded coupler included with the Atari 8-Bit computer version of Robotron 2084. Should come in handy for games that require the use of both joysticks and buttons such as Robotron 2084 on Atari 8-Bit/7800, Solaris, Radar Lock, Stargate, Raiders of the Lost Ark, etc. Tested to work with original CX40s and the new CX40+ offerings, both wired and wireless. Should work with the original CX10 joystick but I did not use one in prototyping. This is a pretty simple and easy to print design that doesn't require supports or a lot of infill. I left a little bit of room in the joystick recesses in the coupler to prevent any potential wear to the joystick enclosures. Feel free to improve or remix the design if you wish.
