LINEAR Chain Slide for garage door opener

This is to replace a part on your LINEAR Garage Door Opener that frequently fails. Print one each of the A and B parts, use your old screw/nut combos. This is the part that attaches to the chain and pulls the outer part that's attached to an arm that lifts/drops the door.

The actual replacement part is on Amazon, but you can use this until you get yours, or until it fails. We've been using the 3d part for several days now, seems solid.

Feedback is welcome.
