Spool holder extension/Spacer

I created this for my Prusa I3 spool holder since the axel´s diameter is much smaller than the filaments one so this is an extension. My spool extension middle hole is 7 mm in diameter an the outside diameter is 53,6 mm.
The outside diameter is bit smaller than the actual one but I used a bit of blue painters tape around the edge so It would fit snuggly and the middle diameter is 1mm bigger than the axels 6mm diameter so It can spin freely. This extension is a 2 part print that you just put to
