Detachable Spool Holder for Anycubic Mega S/Pro and X

thingiverse

OK, meanwhile the Mega models were removed from Anicubic's product portfolio and are sold out. Nevertheless, I would like to present the spool holder that I have now been using for about half a year. My problem was that all my printers are very close to a wall. To change the filament spool, I always had to turn the printer away from the wall to get the space I needed to remove the spool. My solution was this filament spool holder, which you can simply pull upwards out of the mounting block to change the filament and then just as easily put back into the mounting block with a new filament spool. I designed two different mounting arms, one turned outward for the Mega X and one straight that fits Mega S and Pro. I printed everything with PETG. The holding arms and the roll were printed with 60% infill density and 0.15mm layer height. The roll holder I also printed with 60% infill, but here layers of 0.2mm were enough for me. The mounting block I printed with 25% infill and 0.2mm layer height. The arms and the roll holder should be placed on the print bed turned on their side, the 3D models of the mounting block and roll already have the ideal orientation for 3D printing. For printing the arms supports are required. Four M4x25 hexagon bolts with nuts and one M8x100 hexagon bolt with nut are required to assemble the spool holder. Assembly sequence: First insert the small hex screws and the M8 nut to the roll holder. Then fasten the roll to the holder with the M8 screw. Finally, mount the arm on the roll holder. To attach the mounting block to your anycubic printer - where the original holder is also mounted - the four existing short M3 Allen screws must be replaced by M3x12 hexagon socket screws. I had originally planned to use two 688-2RS ball bearings (8x16x5mm) for the roll. But these are not needed, because all filament spools rotate on the axle without the ball bearings.
