Creality K1 Max Riser - Improved Filament Path

Modified riser that provides a much cleaner and pinch free route for the filament, especially if printing from a dryer/drybox.

Two options. A simpler one with the tube mostly floating and one with an arm that provides support to the tube at all times.

I'm still refining the model so will post updates later.

The bearings used are 4mmx9mmx4mm 684ZZ type.

I've added my test version that I had working while waiting on the bearings to arrive. It just uses M4 bolts/setscrews. It works well but assuming it will wear over time.
