Printhead replacement.
Based on hreedijk's request I designed a minimal printhead carriage to support two extrusion heads. This model got the same M1...4x1 thread so you can use the same cap & tightening bolt I made for the original one.
Sorry for the lame object - I just started to learn Fusion 360 what I used to model the carriage.
I just printed it out but did not test at all.
