Spool Adapter for Prusa i3 MK2S spool Holder Suits CCDIY Spool 57mm to 18mm holder

thingiverse

A compact adapter for a 57mm hole spool. I designed this to fit perfectly with the spool holder included in the MK2S kit, which may also come with other Prusa models. Print two adapters and insert them into the spool holes. I chose a 0.4 layer height to provide sufficient grip on the adapter, and believe that a 0.6 layer height would have been even more effective. I printed the adapters with 50% infill, but any infill level above 20% should work just as well. This adapter was specifically created for the CCDIY spools of filament I recently purchased.
