About this model

I'm Actively using this now but it needs a lot of work. I'm working on redesigning this all in fusion and will upload better models, fixing the many issues as I do. The stand is there to raise the filament rolls above the heads and USB cables allowing the filament to be loaded from the top, instead of the side. There is room for 4 containers holding Filament, I am working on making these airtight to protect against humidity. There are 3 holes in the back that will have plugs to keep humidity out when not in use. 1 for a feeder on the right, 1 for a feeder on the left, and a top center one for TPU to exit and go straight to the tube for manual loading. I still need to finish and print, then redesign the back support which will be used to router the Filament tubes from the feeder to the head…
