Small Reels for Loose Filament

These will fit the Replicator 1 & 2 spool holder and maybe others. They have a 60mm (30mm radius) mounting hole. And a 120mm (60mm radius) outer ring.

These perfectly hold the 50M length (137g) loose rolls of filament.

The 2 half's push together (takes a little pressure) and stay together nicely.
