An Ubis Hotend I modeled to assist me with making extruder mounts for various printer designs. I use this model to cut the shape into the designed mount. Sizes should be accurate but to adjust for tolerances I scale the model to 1.05. Modeled in Autodesk Fusion 360 using a reference image found on the Printrbot Forums.
