We have designed a new spool holder design to Thingiverse to hold unspooled material like the beautiful PLA filament from Faberdashery. The design works by utilising the 1lb spool that comes with the MakerBot Replicator 2.
Clip 3 of these spool holder parts onto a 1lb MakerBot material spool like the ones that ship with the Replicator 2. Make sure all of the printed clips are on the side of the spool furthest from the machine to stop it catching the parts on the back of the Bot. You will also want to mount the spool on the left hand side of the Bot, when viewed from the front (opposite side of the Bot to the power switch), so that it does not catch the power cable. As this will be a larger diameter than the usual spools you can leave the filament guide tube on the right hand side, when vied from the front, of the extruder cable.
This part was designed and tested on the Replicator 2 using Faberdashery material .
