Twist-In Ender 3 T-Nut

thingiverse

I created this twist in T-nut which fits into the Ender3 T-slots. Simply insert the holder horizontally and twist it until friction holds it in place. This is useful because you don't need any fasteners, and don't need to remove the endcaps in order to mount virtually anything anywhere on your Ender3 frame. For example, I modified a Raspberry Pi Case to accept square pegs to mount my Pi below the print bed. I chose square pegs to make it easier to grip and twist the fasteners with small pliers, but in reality the design is very simple and can easily be modified to accommodate whatever shape you want.
