Filament holder for the ultimate spool adapter

I realy love the fastswitch ultimate spool adapter by vidschofelix (http://www.thingiverse.com/thing:1874612).
The original anet filament holder doesn't spin realy smooth, so made this design with 608 bearings.
You need:
- 2x 608 ball bearing
- 4x M8 nuts
- 1x threaded bar M8x 150mm
- 4x M3 nuts and screws (spare parts from your A8)

The print isn't nice, had some problems with this filament

Update 2017-03-07:
Added wider base plate
