Simple design that allows you to use a quick connect instead of trimming the tube to lock it in place. The hole in the center needs opened up a little with a .77 inch drill bit. When I made the hole bigger and printed it broke super easy. I was able to just run the bit in by hand. Install the PTFE quick connect first and then push into the holes on the chameleon, but you have to be careful not to snap them. I ended up loosening the motors and then they slid in easier but if you're carful it can be done without loosening. I used petg 5 walls so it'll be solid. Oriented like it is in the picture small side down with supports painted on the bottom of the thick part.
