Large spool holder 2,3kg

The Prusa spool holders that are included with the MMU2, are not wide enough to hold 2,3kg spools.

This large spool holder fixes that problem.

You don't have to buy any new parts. Just print and use the bearings from the original MMU2 spool holder.

See photo for size comparison of different filament spools.

How I Designed This

I measured the size of the original rod, this was wide enough for the large spool.

The problem was the bottom, this was not wide enough.

I've designed a large spool holder, that can use the full width of the original rod.

The fusion360 file is included.
