Fit

• Spool hole diameter must be ≥ 52.5mm
• Spool width can be anything, but this was designed for a 200mm spool

This fit perfectly on my clear Prusa silver PLA spool, but the inner portion was a touch too big for my black Prusament Galaxy Black. I've included my Fusion 360 files so that you can edit the sizes as you see fit.

Assembly

Print the top and bottom pieces separately, then snap together.

Print Instructions

Infill:

0 - No need, it already uses plenty of filament.

Layer Height:

I'd recommend a variable layer height. 0.1-0.15 for the parts that snap together. I used 0.3 for the rest.
