Spool Center Plug
thingiverse
A compact 38mm center-plug was crafted to match my new spools. I sourced top-grade 1.75mm PLA filament from supply3dpla.com. An updated version with a 51.5mm plug is now available. To assemble, print two and insert two 608 ball bearings into the center of the spool. Enjoy!
