Vent position lock for sliding window sash, designed to be compatible with original manufacturer part using 1 inch No. 8 sheet metal screws distanced 50.75mm apart

Changes and improvements from original part include countersunk features for screws, optimization for 3d printing, and use of a M3x6 BHCS as a pin for the moving tab

No supports needed

I was unable to find information on the original part

Update Aug. 14, 2024: Wanted to challenge myself by making a design that didn't require extra hardware, new version with printed hinge uses a piece of filament to reinforce. I cannot recommend the plastic hinge version for anywhere that security is a concern
