M4 T Slot nut

thingiverse

This is an M4 metric T Slot nut, required for fitting into slotted 6mm aluminum profiles. I'm using these nuts for building my new delta printer's frame. The profile visible in photos measures 20x40mm. Print Settings Rafts: Ignore this setting entirely. Supports: Yes, absolutely. Notes: These were printed with supports in ABS material. I produce them at once, printing multiple copies simultaneously. Post-Printing Carefully pull off printing support by hand and very gently smooth the surface using a file. Then insert an M4 nut into the receptacles and it will securely stay due to its low clearance between the printed part and the nut.
