RMU Opening Stop (MMU2S)

As I have my MMU in a Ikea Lack enclosure the PTFE bowdens are located in the right rear, entering the enclosure by a 5mm slit in the acrylic glass.

In order not limit the opening of the RMU (Retractable Management Unit) and thus not fiddling toooo much with the filaments, especially when you have five filaments in, I limited the opening. This also preserves the bowdnes of wearing and getting kinked.

I designed this stop such that you only need to file a bit on the hexagons to fit in the hollow hexagons. Just snap it on without any tools. I additionally added some self adhesive foam strips for softer stop. Works great!
