5 mm - For Renkforce 500 Filament Spools

This tool may help you to center the Renkforce Filament Spool for filaments with 1.75 mm diameter.

You may print it with inlay of 10 %. That's enough for stability.

Lenght is 5 mm. You may print 2-3 of them.

I am using this part for more convenient printing 4 my project.
