Spool Sleeve Adapter

I noticed the spool reel hangs off centre so designed this spool adaptor to allow the spool reel to rotate more central on the Ender 3, to intern help the filament to be unravelled and feed better.

Slides in the reel and easily be removed and swapped between the two max diameter spool hole sizes that I designed. Measure the diameter hole in your filament spool first to make sure it will fit.

Inner holder = 55.2mm max
Outer holder = 74.1mm max (used with the Inner holder)

No supports needed
