Spool holder extension/Spacer

thingiverse

I designed this for my Prusa I3 spool holder because the axle's diameter is significantly smaller than the filament's one so it serves as an extension. My spool extension middle hole is 7 mm in diameter and the outside diameter is 53,6 mm. The outside diameter is slightly smaller than the actual one but I applied a bit of blue painters tape around the edge to ensure a snug fit, and the middle diameter is 1mm larger than the axle's 6mm diameter so it can spin freely. This extension is a two-part print that you simply put together afterwards possibly with some glue but I didn't need any. Keep in mind that this thing might not fit every kind of filament spool or spool holder.
