Genie Screw Drive Garage Door Opener Coupler

This is a replacement insert for the factory coupler in screw drive style Genie garage door openers.  You will need to heat the original stripped coupler and press the plastic piece out of the steel sleeve, then you can push this printed piece into the original steel sleeve thereby repairing the coupler.  Depending on your printer accuracy you may need to tweak the settings a bit as this is designed to be a minor interference fit.  I printed it out of polycarbonate for durability, but I suspect PETG would work as well (un-tested by me.)
