Assembly mini-spool (150 mm)

Simple three-part mini-spool (diameter 150 mm).
The thickness of the spool depends on the screws selected (screw M3x30 for spool 23 mm, M3x40 for spool 33 mm).

Auxiliary fasteners:
3x round head screw M3x30
or
3x round head screw M3x40
and
3x nut M3 (thickness 2-3 mm)

This is a remix of an even more compact model.
This version will be convenient to print on either a small printer or, conversely, a printer with a print bed area of ​​300 x 300 mm.
