Sunhokey Prusa i3 Hot End Bracket

This is the first version of my new hot end bracket for a Sunhokey Prusa i3. Basically the frame is stiffer than the original and has space for an extra SC8UU bearing (they are about $2 each off eBay) which stops the bearings rocking.

There are spaces for the GT2 timing belt, hot end fan and bracket, and for both X-axis limit switches.

It was designed with minimal filament consumption in mind.

A new version that I am developing is here: http://www.thingiverse.com/thing:1287974
