Twist-In Ender 3 T-Nut

thingiverse

I designed a custom T-nut modification for my Ender3 that allows me to attach any object directly to its frame without using any additional hardware or removing endcaps. To install it, I simply insert the holder horizontally into the T-slot and twist it until friction secures it in place. This clever solution eliminates the need for fasteners and gives me the freedom to mount virtually anything anywhere on my Ender3's frame. For instance, I created a custom Raspberry Pi Case that accepts square pegs, allowing me to position my Pi below the print bed with ease. The use of square pegs makes it simpler to grip and twist them using small pliers, but the design is actually quite straightforward and can be easily adapted to fit any shape or configuration.
