RODAM Ender 3 Spool Holder - Fat Mod

thingiverse

As many of you may have observed, the spool has a tendency to sway freely when all support is concentrated along a single axis. This occurs even with ball-bearing spool holders. Despite using spool holders that feature ball bearings, I still experience some swaying. I reworked this version of the RODAM Ender 3 Spool Holder designed by Rodamyot (https://www.thingiverse.com/thing:3502973) and relocated the bearings from their central position to create four support points distributed in such a way that no swaying is possible. Following installation, my setup operates flawlessly. The filament spins slowly as it's drawn by the extruder, with no jerky movements caused by a swaying spool. To ensure all four bearings make contact with the spool (my spools measure 65mm), I created two versions: a longer one measuring 85mm and a shorter version measuring 70mm. I combined this design with Emolan's remix (https://www.thingiverse.com/thing:3979065) to produce bayonet versions compatible with the original nut. Lastly, I developed an AntiSpin version of the dowel, which prevents spinning within the slot as reported by users who experienced issues when their prints didn't fit tightly enough. To guarantee a strong print, it's recommended that you use thick walls (perhaps 2mm) during printing.
