A basic adjustable spool holder which clips onto the side hand hole on the 2015 FlashForge Creator Pro (may fit similar like Makerbot etc). I had some old skateboard bearing so i figured i could use them - this is mainly for specialty filament that you dont want or need to feed through the feeder tubes - especially flexible filament - it just feeds straight into the extruder assembly. Requires the following Hardware:

1. 4 x (skateboard bearings) 608 bearings
2. 2 x 150mm m8 bolts or threaded rod
3. 8 x m8 nuts

Print the Left and the Right, then press the bearings in each side, slide the bolts through and your done! Can be adjusted for skinnier rolls if required and simply lifts off when not in use.
