another spool holder..

just like the title, it's another spool holder I made.. It's just that I can't really find the spool holder that I want, so I made my own.

This spool holder should fit almost any filament spool out there, maximum 1 kg filament, I'm not sure if it can hold 2 kg. Also, any big spool with tiny center hole should not fit as well.

There're 3 slots to fit small cylinder magnet at the back side so you can secure the mount on your whatever metal surface you wanna place your spool holder (in my case it's the metal housing of my Printrbot)
