XHTC / extremely simple automatic head changer

I can finally say that this design is perfect for publication. The XHTC is an automatic tool changer based on Renè Jurack's design. To see the procedure for this design I can only recommend the video. There is also a playlist where you can get more information. The design of the STL files is finished, but the whole cabling and control is not yet.
