Overlord 3D Printer - Simple big filament roll holder

thingiverse

This addon lets you use any big filament spool that does not fit the Overlord's filament housing. It works. Maybe not as good as other holders, but it is simpler: just one part, no assembling, no supports, no nuts, bolts, metallic bars... Just print and use. Instructions I did print it with ABS, 80mm/s, infill 10%, no supports, small brim to improve bed adhesion. Once printed, remove brim and put it inside central hole of the top filament housing. See pictures. If your printer is not well calibrated for dimensional accuracy, or your printer's hollow tube has a smaller inner diameter than 26mm, you may need to scale it down a bit before printing. Of course, print it with the big flat cilinder facing down.
