Makita 18V battery holder screw in-latch free

A Makita 18V battery holder that is latch free and can be screwed in anywhere. I made it latch free so it is super simple to use. Battery just slides right on and slides right off. I made the tolerance pretty tight so that it doesnt rattle or have any wiggle room. The fasteners that should be used to attach are flat head countersunk screws.

I made mine from PTEG so it has slightly better temp resistance in the summer and in my hot garage, but any filament works. 

Let me know if you have any questions or suggestions for improvement
