Extra grip for the bit of the "nyloc mod helper"

prusaprinters

Added some more grip for the bit. Now the dial holds the bit more firmly. This only replaces "nylon_mod_point.stl". Use the existing "nylon_mod_base.stl". Print instructionsUsed 3 perimeters, which gives a more firm grip for the bit. It basically produces a solid bit holder. I sliced the file for my MMU2S. Extruder 1 is for most of the object, extruder 2 for the pointer only. Done as layer changes with a sparse waste tower. The project file (nylon_mod_point_extra.3mf) easily allows to add the original base (not modified), as its color change needs are at the same height. Non-MMU2 owners can modify the automatic filament transitions by prompts for manual filament changes.
