About this 3D model

I made my own Version of a Printhead for the E3D also for the Default UM. Both of the Heads are Screwed to the bearings. So i don't have to disassemble the whole UM to get the Head of and changed. This Thing is still work in progress. So far i printed and assembled it. I did not mount it to the UM so far. I will Update this Thing, if my tests show this Thing is good. I still need to create a Fan mount for it. ###UPDATE: I have my new linear bearings now. I tried to mount the head to the UM. It fits the Rod, and seems to work. Problem: The X, Y and Z endswitches need to be repositioned. I will redesign the Head ones more, and try to make a Version, where the default end switches will fit. ###UPDATE 2: Added new Version. There is a Version with no Support needed, but the linear-bearing will not be covered on the full length. Also there is a version where 2 Parts need Support to be printed. I removed some screws and added some kind of clip on. Also i moved the axes nearer to the hot part, so less spaces is used. I hope this fits with the default end-switches. ###UPDATE 2.1: Fixed some issues with - Axis Clip 2 - Big Part - No Support - Big Part ####Both Versions need: - Head Mount.stl - Axis Clip 2.stl ####No Support Version needs in addition: - Big Part - No Support.stl - Axis Clip 1 - No Support.stl ####If prefer the full coverage of the bearing: - Big Part.stl - Axis Clip 1.stl I need to print and test it. But the printer is busy and get direct drives first. ###TODOS: 1.) Add a construction to mount the vent 2.) Live tests and try to print hot (ABS)
