I remixed the “Filler” spool holder to a compact form factor that was drop-in compatible with the Raise3d Pro2 and Pro2Plus machines.

The stock spool holders on the Raise3d Pro2 machines were plastic semi-cylinders. Over the course of printing, 10 rolls of filament through the machine, white particulate, and debris were generated due to the friction and mechanical wear of the plastic spool real and the plastic spool holder. I wanted to eliminate this debris generation as well as reduce the drag caused by this friction.  

I have since put another 20 rolls of filament through the machine and seen no debris generation or ill effects due to this upgrade spool holder.

Requires:

1x  Spool Holder
1x  Roller
2x 608 bearings “Skate bearings”

I printed mine in PLA with 4 perimeters and 25% infill. Your mileage may vary.
