Eco3D Filament Spool Hole Reduction for original PRUSA i3 Printer
I started to use filaments from new source:
and I wanted to make the reduction for the spools as well. So I remixed my original Prusa filament spool reduction.
Reduction_ECO_big_hole.stl is for 0.25kg filament spool.
Reduction_ECO_small_hole.stl is for 1 kg filament spool.
Btw, check them out if you want. They make good filaments.
While I was into it I added universal Scad file for your convenience. You just edit three basic variables and produce your own different size spool reduction.
Diameter of the spool hole.
Width of the rim in spool hole.
Diameter of spindle of spool holder.
and thats it.
