T-Slot T Profile Nuts
thingiverse
This type of T-nut must be slid in from the top of the extrusion. It does not allow for any rotation so it cannot be inserted from the side. Use the pull-through method to seat an M3 nut in the hexagonal hole. I wanted to attach a handle to my Prusa Mini clone, but I didn't have any more of those slide-in T Profile nuts. So I made one.
