I designed this vertical mount to clean up my BMCU setup and save desk space. The support slides onto the unit's sides and clamps onto a horizontal bar using two grub screws. This design lets you lock it at a custom tilt angle to get the smoothest filament path for your specific workstation. The base is secured with two screws to any flat surface. It works with any suitably sized bar and helps prevent PTFE kinks by maintaining a natural curvature for all 4 modules. Check it out!
