Gridfinity 1x1 module Freecad source

I needed a Gridfinity base for my headlamp charger docks, but couldn't find one without necessarily restrictive licenses so I whipped this one up. Do whatever you want with it, but please give me a shoutout.

Free template to use to create other 1x1 Gridfinity modules in freecad. Can also be placed next to each other to make bigger bases.
