Air-buffer for Prusa Enclosure V2 - MMU3

My requirements: simple workflow to load/unload filament possibility to manually push/pull the filaments to fix failed loads/unloads (yes it happens) weights guided during printing (and always tidy and at hand when unused) weights can be installed/uninstalled while filament is loaded whole setup attached to the enclosure (and therefore movable with it) quick and tool free disassembly of the printer reliable… hopefully All parts printed in PETG except end-caps in TPU.
