About this 3D model

I take my extruder on and off my Prusa to change out the hot ends often. I love Greg’s X carriage, but I find it takes some fiddling to retighten the belts. After seeing this, neat thing http://www.thingiverse.com/thing:16730 I wanted to try to build that concept into the X carriage, and while I was at it, try to reduce the hardware parts count. I tried to utilize the concept of a Drop Clamp which self tightens as strain is put on the wire. My thing is fixed on one side of the x carriage, and the other side uses the self tightening idea. As an afterthought I added one screw, and bolt hole (M4 or 6-32) to use if required to add a bit more tension if your belt still has some slop. The LM8UU bearing holder was copied from this thing, and then modified to suit my needs. http://www.thingiverse.com/thing:15219 This was more an experiment to try the idea, as opposed to a finished product. I wanted to share with the community in the hopes that maybe it might inspire someone to build on the concept and reduce the hardware count.
