one sided filament spool holder

thingiverse

Simple filament spool holder with one open side for effortless spool replacement. I utilized two plastic bearings I had readily available (Igus BB-629-B180-10-ES / d9 D26 w8 and BB-I-1636-12-B180-10 / d12,5 / D28,5 / B9,6) to create a free-spinning hub at no cost. Sorry for the imperial measurement. -> https://www.igus.de/xiros/kugellager?sort=3&inch=false A hot air gun was used to heat up the hub for easier placement of the bearings; it's a relatively tight fit. Secured with one M4 x 60 screw and a M5 washer, supported by two M4 lock nuts for enhanced stability in the stand. It works well, offering lower resistance than traditional filament rolls on steel axles. I've included the step files and native Solidworks files if you'd like to modify them. When printing it lying down on its back, minimal supports are required for the stand – only one in the lock nut hole is necessary; no supports are needed for the hub or spacer. Consider adding a rubber pad to the bottom if it moves excessively. Best regards, Sebastian
