A simple support bracket to use to suspend your filament reels underneath a shelf.Just source a suitable metal spindle and print to interference fit - I used an old support leg for a fibreglass bathtub! STL is for a 19mm diameter spindle, or download the OpenSCAD file and tailor with a simple variable change. Suitable for 200mm diameter reels. Print with a suitable strengthy infill, I would recommend 20%+ infill with a rectilinear or hexagonal pattern.
