This is a hot end mount for an extended printrbot simple with a bowden extruder. The J-Head mount is designed to fit what I believe is a cheap E3D clone, so this might work with an E3D hot end (currently unconfirmed). The Ubis mount is designed to hold a fairly large bowden coupler above an ubis hot end. (I will try to update this with more detailed information about what coupler it's designed for)

To use this, I recommend hot gluing the Y endstop to a new location as well as gluing on a piece of a scrap print. I think if you look at the picture of my endstop setup (which I only needed hot glue to create), it should be pretty simple.

I designed this, like all my other parts, in Tinkercad. If you're not experienced with CAD at all, I highly recommend learning Tinkercad, because it's free, super easy, and powerful enough to design some really cool stuff.
