Oversized spool holder for Ultimaker Material Station

thingiverse

Ever notice that some 1-kilo filament spools are a biiit too thick to fit into the Ultimaker material station? I have a solution. This is a set of arms that ziptie on to the idler rollers in the #1 and #3 spool bays. Your oversized spool is suspended on an axle between them, and feeds into one of bay #2's filament holes. The axle is pinned in place with two printed pins. (This does mean you have to leave the material station door open while printing, allowing moisture in. This is the moisture equivalent of leaving your fridge door open, and I don't yet know what the long-term consequences of this will be, but I'm just using it for short prints for now.) When you're not using it, remove the pins and the axle, and the two arms fold up neatly into the #1 and #3 bays. This consists of three parts: (2x) Folding arms, ums5-spool-holder-normal.stl (2x) 3D printed pins, printer-spool-pin.stl (1x) axle, either print pipe-with-holes.stl, or cut an 8.5" length of 1/2" PVC pipe and drill two 1/4" holes through it (see drawing). The PVC pipe is preferred to a printed axle because it's smoother and rounder. Print settings are whatever, you can probably use regular PLA for all of this, use enough perimeters that the axle and arms don't crumple under the weight of a spool.
