Prusa i3 Bowden mounts

The Prusa i3 is still very new, and lacked a good single-hotend mount. I designed this mount for the Ubis hot end to work with my self-sourced Prusa i3 using 1.75 mm filament. The Ubis hot end has a groove that is mostly compatible with the J-head, at least according to google searches. This means that this mount should be fully compatible with J-head grooves as well. Included are two hot end mount variants, and a cold end bracket.

For the hot end mount, I initially chose the screw hole hot end mount method that most extruders use. However, after reading this thread: http://forums.reprap.org/read.php?1,238528, I decided that a tight fitting groove mount made more sense, and redesigned my mount. Both versions are included. It is possible to adjust the height and depth of the mount, all accessible in the included SCAD files.

The cold end mount attaches to the Prusa i3 sgraber frame, and holds the cold end up. I recommend this extruder: http://www.thingiverse.com/thing:34503. For t
