3kg Spool Holder for Prusa Printer MK3s

This is a simple Spool Holder for the Prusa MK3s Printer that will hold up to a 3kg roll of filament. Also works just fine for 1, 2, 2.5kg spools.  This design aligns the spool of filament so that it minimizes the flex on the steel frame due to the extra weight.

Included are two files, print two "SpoolHolder" and one "SpoolHolder-shaft". In place of the shaft you might also opt to use a 3/4" piece of PVC pipe.

Print instructions

.4 Nozzle

Layer Height: shouldn't matter

Perimeters: 11
Note: You want a very strong perimeter for the holders or it might flex or otherwise not support the weight. I printed it nearly solid with Perimeters. The shaft only needs perimeters of 5 or 6.

Infill: Should not matter if you have enough perimeters.

Infill pattern Grid

Total Print time at these settings is roughly 17 hours.

Note: Its been reported this does not work with the MK4 version of the Prusa printer.   So I would advise against printing it for that printer at this time.
