T3P3 Kossel Release 3 Hotend with nut slots

thingiverse

I got fed up with the "threads" in my T3P3 kossel's hotend holder stripping every time I tried to tighten the m3 bolts to a decent amount, so I modified the openSCAD source file for the part to include some cut-outs specifically designed for m3 nuts. I made sure to print with enough solid top/bottom layers to ensure that the plastic between the nut and the effector is solid as a rock. I highly recommend using washers on the bolts to prevent crushing the plastic of the effector at all costs. I use m3 nyloc nuts by threading m3 bolts through them, allowing me to pull the nuts into place before tightening with ease. source: https://github.com/T3P3/kossel The license is actually GPL3, not GPL2: https://github.com/T3P3/kossel/blob/master/LICENSE The STL you want is Kossel-Hotend-With-Cutouts3.stl
