Sandblaster Caster Bracket

Harbor Freight sandblaster cabinets sit on four fixed angle-iron legs. Moving one usually means lifting a heavy, awkward machine. Andbru designed an L-shaped caster bracket that sleeves onto the outside corner of each leg and gives a plate underneath for common caster bolt patterns.

Once the brackets are on, the cabinet rolls. The receiver is a true L — two walls wrapping the leg corner — not a U-channel or closed socket, so it installs cleanly on the stock Central Pneumatic cabinet without redesigning the machine.

The design was strength-checked in SolidWorks Simulation under a representative leg load, then produced and shipped as a finished product. It is already on the market through eBay — a full path from CAD to a part people can buy and install.
