Prusa I3 Steel Spool Holder

thingiverse

This spool holder is designed especially for the Prusa I3 Steel, it allows rapid change of the spool, since it is enough to put it over. As it does not invade the front of the printer it does not cause interference with the extruder if the piece is very high. The horizontal bars are M8 threaded rod with 608 zz bearings at the lateral ends for smooth rotation. To keep the filament spool stable, I passed 2 aluminium pipes of 10mm external diameter over the bars. Instructions Materials: 4- 608zz bearings 22x8x7 mm. 2- M8 threaded rods 256 mm long. 2- 10 mm external aluminium pipes 223 mm long. 8- 8 mm washer. 6- M8 lock nuts. 2- M8x25 screws
