Modular Ceiling Storage Mounts for HDX 27G Totes Just uploaded a new functional design to clear up floor space. If you use those HDX 27-Gallon totes, I designed a modular rail system to hang them securely from the ceiling. I highly recommend printing them in PETG, ABS, or ASA to survive high summer garage temperatures. For the strongest part, use 5-6 perimeter walls rather than relying on high infill. Make sure you anchor these directly into ceiling joists with lag screws.
