Prusa I3 Steel Spool Holder

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.
