4-axis modification for MK3s with rotational printing head

Warning: this mod is experimental and needs engineering and mechanical background to build. No guarantee and very little support provided by me.

This is a modification you can add to your MK3s to be able to print 90° overhangs without support material. The nozzle is tilted 45° and an additional rotational axis is provided.

The .stp and .stl files to all parts, that can be printed are provided. Also the drawings of the parts, that have to be machined. A BOM gives you an overview on the parts, we used to build (please be aware, that some of the parts are no longer available under the given link). And there is also a document, that shows you how to assemble everything. 

But be aware: this mod is experimental and needs engineering and mechanical background to build. No guarantee and very little support provided by me.
