Storehouse Bin Builder designs custom 3D-printable bins for Harbor Freight’s STOREHOUSE parts cases. You draw bins on a map of the case floor, check them in 3D, and download all the STLs in one zip. It runs in your browser, with no install and no account.
Features
- Both case sizes. It works with the 20-bin Medium and 8-bin Large cases, which share one floor grid of 54 by 40 mm cells.
- Draw on the floor map. Drag across empty cells to make a bin and drag a bin to move it. Start from the stock layout or an empty case.
- Dividers, labels and feet. Each bin can have dividers, a label and the stock bins’ round feet. A label prints as raised letters on a small shelf you can read through the lid.
- Stacked bins. Split a slot into a short bin with a tray on top for two levels in one slot. The lid still closes, and the tray prints without supports.
- Fit you can tune. The walls copy the stock bins’ 1.5° taper, measured with calipers. A clearance setting and a fit-test download let you match your printer.
- One zip per layout. Matching bins share one STL, and a layout file tells you how many of each to print.
- OpenSCAD version. The repository includes an OpenSCAD file that builds the same bins, and the app copies your settings into it.
