Sliding Door Track Lock - parametric

Lock a sliding door or prevent a sliding door from opening too far with this track lock.

I have uploaded STLs for M3 and M4 bolts, but the scad file is fully parametric if you'd like to adjust it further.

#### Hardware
Bolts M3 or M4, 16mm length or longer. Nuts are press fit, shouldn't need a soldering iron.

#### Printing
I printed this in PETG with 15% infill. Printed as the model is, with the U channel pointing up. No supports, Orca put a brim on it.

I'll update this if the print fails. Slightly worried about the U channel's sides cracking due to layer lines.

#### AI Disclosure
Initial design was generated by Claude Sonnet 4.6, but I had to massage it a little to get everything right. I wouldn't consider this AI slop though.
