This is a version of the MMU designed to use filament dry-boxes. It uses rivnuts (https://www.bunnings.com.au/kincrome-m4-20-piece-rivnut-set_p5910348) instead of a typical PTFE tube connector.

It uses most of the same components as the original Shark.

The base supports are a fairly elaborate shape so that I could re-use the original panels I had cut for the original design.

The shark fin components replace the original loading lever and prevent filament getting bunched up at the entrance.
