MakerBot pen holder (1 piece)

thingiverse

This pen holder for MakerBot has a unique design compared to other similar items on Thingiverse. The key difference is that it's made up of just one part, simplifying the printing process. There are two STL files available - 'Stifthalter_1part.stl', which is angled at 45° for easy platform fitting and is best printed without a raft; and 'Stifthaler_1part_horizontal.stl', arranged horizontally to minimize raft size but requiring more build platform width. After printing, insert your pen and use an M3 bolt/nut if needed for clamp tightening. Finally, attach the holder to your MakerBot's Z stage using two M5 bolts, just like with the dinosaur attachments.
