universal spool holder EVO for 24 - 56mm holes

This is a new version of the universal spool holder, for 24 - 56mm holed filament spools. It's a logical fusion from the original spool holder (http://www.thingiverse.com/thing:127181) and the spoolock (http://www.thingiverse.com/thing:2124918). You don't need any nuts or tools, just mount it on a 8mm threaded or plain rod to hold the filament spool on it's place.

There is a one part version of the middle part, and a two parts version for easier printing.

For the anti slip inlay use a 10mm
