I tried it at home
thingiverse
This thing was created using Fusion 360 and Inkscape by someone with a passion for DIY projects. For those interested, Angus at Makers Muse has an excellent video on YouTube that covers this well. The printer used has a single extruder and hot end, which is standard equipment. Marlin firmware has been modified to include the change filament capability, which can be triggered by adding a M600 command in the G-code file. I use Cura to slice my prints and view the layers to determine at what layer the M600 needs to be inserted into. Chris Riley on YouTube has a great video that explains how to add M600 to Marlin. Note: This thing is quite thick, so the print in the picture was scaled down on the Z axis when sliced using Cura. Edit Update: Member ASLLEXICON remixed the original design for use with a MMU printer and sent me the STL files used. I also added the Fusion360 file I used for the original, which is a quick and dirty drawing but got the job done.
