Delta printer filament holder

Note... after some consideration Ive decided to do a mk2 of this that will feature a retainer for the races and be 100% printed, ie no steel balls

Horizontal filament holder for a delta printer, This was designed specifically for the RepRapPro Fisher but would be suitable for others, especially if they have a flat top suitable to put the filaments on.

Essentially this is a thrust bearing design, and in fact can be used for a wide range of applications where something needs to rotate.
