Sliding guide thingo width is 3.5mm, to fit a door with a slot of 4mm or greater (ours is about 5mm)

Our plastic door-slide guide broke because someone pushed on it instead of sliding it, repeatedly.

This was quick to model but I went through a few versions figuring out how to best reinforce it and match the existing screw holes, which is why they aren't evenly spaced.

Printed in Anycubic Tough Resin with no supports, this should work in ABS or PETG with no issues either.

Screws inserted after printing but before curing.

3x 15mm long M2 countersunk machine screws are inserted from the bottom after printing, this provides the reinforcement that will stop the part from cracking when someone pushes on the door instead of sliding it.

Has been working great for a few months now.
