Prusa Acrylic, Afinibot, Spool Holder

I made this spool holder to use the space behind the machine,
The shaft is a shaft from the water pump impeller of a FZ8 and the bearings I used are 2 old bearings from that waterpump.

Feel free to modify it to use another shaft/bearings size.
Bearing size : O.D. 28mm
I.D. 12mm

The shaft is a 12mm shaft
