Filament Spool Holder Universal Size

Because I use very different filament spools, I have designed this holder. Spools with a diameter of 100mm to 300mm can be used, and probably larger. The outer width of the spool from 50mm to 100mm. These spools have already been tested. In addition, a smaller version is on file for those who do not use large spools. The small axle holder and axis must be printed twice. The axles are telescopic and have been stored in three variants. The version with 0.2mm gap can be used for precise printers. You can select the version suitable for your printer. The larger gap makes the axes more wobbly, but this does not affect their function. The ball bearings used are 4 x 608RR with a size of 22mmx7mm and a hole of 8mm. The axles can be fixed with an M4x15 countersunk screw. The hole is narrower at the end. This spreads the plastic and fixes the ball bearing. Happy printing!
