Summary

This is a modded version of my Polymaker spool holder that uses the Reel 2 or Filament 2 locating lock ring pegs on the CEL Robox DM 3D printer.

It is roughly 46mm in diameter and 60mm long, so will cover most larger holed filament reels. There is an M6 screw thread, which when used with a washer will acts as a stop to keep the reel on the holder, and all of this still means you can access the filament eject & pause button on the Robox. The spool holder is offset vertically, to raise the centre slightly to improve the feed into the filament 2 gate, and stop the larger diameter reels hitting the deck.
