Filament Spindle for MMU

Using the MMU with my Prusa MK4, I was having issues with my filament spools being pulled off the wheels that they rest on and causing the prints to fail as the filament was unable to be fed to the extruder. I hadn't had any print issues with the initial suspended spindle that came with the MK4, but the way it sits made it impossible to close the enclosure and would also limit me to two filaments loaded at a time. To fix this issue, I decided to combine both designs. I recreated the clip that interfaces with the MMU filament-holder base and added a vertical spindle suspension similar to the printer default. This setup allows filament storage outside the printer enclosure but eliminates the issue with it coming up the track. You will want to print vertically (annoying with how much support is required) because otherwise the clips will break when you try to install the spindle onto the base. Also, the model could be modified with the feed holes made slightly smaller to better match up with the plastic tubing that leads to the MMU (current model the tubing can slide through the hole. It doesn't seem to affect the print but isn't as visually appealing).
