The printer I use with the 3D Chameleon is way up high on a shelf. I created some simple stepper motor rotators so I can see when filament is being driven in/out and also what filament is being unloaded and loaded. There is an oversize gear for the extruder and a windmill for the selector (sorry I didn't have that exactly aligned for this video, needed 3 hands! but you get the idea). Video of it in action: https://streamable.com/4vptya I used a pressure-fit 8x3mm neodymium magnets I ordered on ebay:

If the 3DClippy is mounted to x home, how do you keep it from cutting the filament every time you start a print? Can you mount it in a mirror image and use x max instead?

I hate to ask such a simple question, but how do you duplicate a working printer profile in Cura 5.0? I have a brand new Anycubic Kobra Max. I used an Anycubic Viper profile and just changed the bed size and have been getting good single filament prints. However, this doesn't allow me to change the number of extruders or anything. If I just copy all the settings to a custom FFF printer, it doesn't seem to work as well as the Viper profile.
