RODAM Ender 3 Spool Holder - Fat Mod

thingiverse

As you all may have noticed, the spool has a tendency to dangle, when all the support is distributed along a single axis, even with spool holders using ball bearings, I still get some dangling. I remixed this version of the RODAM Ender 3 Spool Holder, by Rodamyot (https://www.thingiverse.com/thing:3502973), and moved the bearings out from center, to create 4 support points, distributed such that no dangling is possible. I've just installed mine, and it works like a charm. :) Now the filament spins slowly as the filament is pulled by the extruder, and no jerks from a dangling spool. I created 2 different version, a long (85mm) and a short (70mm), to make sure all four of the bearings are touching the spool (my spools are 65mm). I also mixed this with Emolan's remix (https://www.thingiverse.com/thing:3979065) to make bayonet versions, that will work with the original nut. Lastly, I created an AntiSpin version of the dowel, that will prevent spinning in the slot, as some users had reported the original would do, if they we're not a tight enough fit. NB: To ensure a strong print, I suggest you print this with thick walls (maybe 2mm)
