PLA Spool Centres

This is a 100mm centre for the spool that Diamond Age Solutions supply their 500m spools of 3mm and 1.8mm PLA, and 1.75mm ABS on. Each centre takes a 608 bearing, and a piece of M8 rod goes through the middle. A set of locknuts on each side keeps the centres in place.

The file is parametric so you can change diameters to suit.
