At FilamentColors.xyz, we print a lot of samples, and the Prusa Mini has quickly become one of our best machines for it. The design of the Mini means that it can't support a full spoolholder... but it can support a little weight (~100g or so).

This little add-on gives support to the Expandable Sample Spool and allows you to mount small amounts of filament directly onto the Prusa Mini with no degradation of performance!

You will need the following things:

• Mount: [https://www.thingiverse.com/thing:3250547](https://www.thingiverse.com/thing:3250547)
• 2x M5x10 cap head screws
• 2x M5 3030 T-nuts
  • If you don't have access to metal 3030 nuts, these work great: [https://www.thingiverse.com/thing:3663001](https://www.thingiverse.com/thing:3663001)

Print instructions

Print upside-down -- see the slicer image for reference. You will need support to handle the curved section, but that should be it.
