This model allows the user to place both Snapmaker U1 autofeeders in the same side of the printer.Required hardware: 4-6 M4 10mm screws4-6 M4 washers4-6 M4 T-Nuts12cm 2020 profile (as arm, a printed one is fine just look for it in MakerWold). You will also need to build an extension cable for one of the feeders. The design is made with M4 screws in mind, but I've uploaded a M3 and M3x2 rail designs just in case you prefer it.
