Spool spacers for reuse, rewind last meters to save space

Printing

• Use “draft” mode, with layer height 0.30 or 0.25.
• Enable brim, to be completely sure also set type to “inner and outer brim”

Designed for a friction fit, though you can use M4 screws from the side as well.

Use:

• IMPORTANT: for the 530gr version only, you need to partly saw off ONE side piece (see pictures)
• the other sizes work with unmodified spool sides, just slide off the original cardboard and slide on

If you need other sizes, just scale the model in Z-height in your slicer (60mm high is for 1kg)
