Cục chặn cuối thanh ray DIN cho terminal

This is a small wiring terminal endstop, to keep them straight, and also doesnt let them slide around.

It utilises two screws instead of an angled one.. The screws are self tapping into the plactic.
The endstop can be simply snapped onto the rail because of the small bending tab, also you can remove it with a flathead screwdriver by bending it backwards.

Hardware: 
2pcs M3 20mm screw

I recommend to print it in PETG.
