Spool holder bracket made for Prusa I3 Mk3

WARNING: High Strength Spool Rack Holder Alert! If your print extends all the way to the top of the build area, you risk a catastrophic collision. This robust spool rack holder is specifically designed for Prusa I3 MK 3 printers and should be compatible with other Prusa I3 models that feature the same top bar frame. When paired with a standard-sized spool and a 1.9-inch diameter PVC tube, it provides ample clearance to enable normal MMU operation. A single unit of this holder can support up to two spools securely, but if you install two, they will be more than capable of holding eight spools without any issues. Once printed, the hinged joint allows for easy removal from the print bed and bending into place, securing the supports with a snug fit. The 1/20-inch gap between moving parts ensures a precise fit.
