Prusa / Prusa i3/ Mendel / Reprap / Printrbot DDE Spring Lever Drive v1.6, UBIS hot End, Others with Mods

I really liked the simple system used on the new Replicator extruder set up so decided to re-create it for the Printrbot and generic RepRap style machines.

This unit is designed to fit a UBIS style hot end, but can be easily modded to take a J head or whatever else.

This will bolt straight onto a Prusa i3, and should fit any other generic Reprap style machine, maybe with minor mods..

This is a new iteration of my previous design with improvements.
