Adapter Ring for Sunlu Master Spools (Blue and Clear)

This adapter was designed for use with my Sunlu Master Spools. It is 63.25mm diameter for a snug fit with a bevelled edge for easier insertion to the spool core. Printed with 4 walls and 10% Infill using PETG. Very snug and solid. While the Sunlu Master Spools are only 63mm internal diameter, I've found that the extra .25mm is necessary for shrinkage for a snug fit. The only improvement I'd see beyond this would be to find a keying option to rely on my than just friction, but this works remarkably well.
