Skater Spool Holder - CTC - Flashforge - Wanhao - Replicator

Aurarum my local suppler for filament uses a spool with a smaller core size of 30mm rather than what my CTC printer's original spool holder can hold, which is about 38mm and up.

I couldn't find an alternative in the 'verse to suit my needs so i made my own using some rather long 150mm M8 Bolts and some skateboard bearings.

Now I can use both sizes of spool and there is practically no rolling resistance. Woot!
