Chamberlain Sprocket Coupler

This is the coupler that connects the motor and the screw rod for a garage door. it should fit all Liftmaster Screw Drive and Low Profile Screw Drive operators (1995-current), models 1000SD, 2000SD, 1000SDR, 2000SDR, 2110, 2220, and models 4600, 4620, 4640, 9902, PD420, PD460.

This part was made as a replacement using the original that I super-glued together to get some measurements off of. I printed mine in green PETG because that's the only PETG I own as I do not prefer to print with it. 

This part is printed with 100% infill to make sure it can withstand long-term use. It works great, we have been using it for a little bit now and put it through some rough use, because there was more wrong with our door than we knew.

Happy Printing!
