Filaments.ca Cardboard Spool Rim for 2022 Spools

Filaments.ca Cardboard Spool Rim for Spools made in 2022 to early 2023. Inspired by the Polymaker cardboard spool rims. 

I found that several large orders of spools from filaments.ca had issues with delamination, not to mention a fair number of them arrived already dented on delivery. The cardboard spool rails can help remedy common problems such as damage, delamination, and cardboard dust.

It looks like Filaments.ca keeps changing their spool design, so compare your spool against the image to check compatibility before printing.
