I thought the Assassins Knives on Thingiverse were so cool, and I saw some people doing frames, but no one had the stl for them, so I made one myself. This is designed to be a simple manual color swap using layer pause, and can be thrown in MMU. I printed with a 0.4 nozzle at 0.2 layer height. This is designed to print on a 300x300 bed, but I made it two parts so if you shrink it to 90% it will fit on a Bambu plate with each part separate.
