Spool Hub · 模型 276742
I've designed & printed 2 spool hubs for my printer. They are printed out of PLA at .15mm layer height. They are press fit onto a 0.375 inch drill rod and hold the filament spool on center. The hub center hole ID is 0.375 inches. The printed ID was slightly smaller so I ran a 0.375 inch drill through the parts to clean them up. The assembly fits perfectly on the PRUSA i3 MK2 spool arms that came with the printer. The spool now turns smoothly as the printer pulls in the filament, instead of the hopping the spool used to make.
