Set the inside size
Enter the clear inside size you need. Outside size is calculated automatically.
Body outside size: 123.2 × 90.6 × 66.6 mm
Type any value directly. Slider ranges expand to match it.
Hooks use a plain L profile directly from the back. A 2.4 mm inner radius, wide root, and lowest-row hooks distribute load.
Enter 2 to split in half. Fine-tune positions in the top view.

1.6 mm: suitable for ordinary small-item storage
0 mm keeps a level opening. Keeps the back height and slopes down toward the front. Dimensions refer to the box before removing walls.Removes the floor. Useful for surrounding an item on a desk or routing cables underneath.Hooks
4.0 mm is the PLA default. The whole back supports the hooks without bulging into the box or board side; inside size stays unchanged.
For a 5 mm slot, hook width is 3.7 mm (1.3 mm total side clearance). It clears 5.3 mm of board and engages 6.4 mm behind it.
Depth is applied uniformly to the vertical leg of the L. A deeper hook resists lift-out but needs more clearance behind the board. The default is 6.4 mm.Choose the best slot-width value and board-thickness value from the gauge.
Current fit: slot 0.7 / board 0.3. Fine-tune the numeric fields above.
Measured reference: slots about 5 × 15 mm, board about 5 mm, vertical pitch 40 mm. Locking hooks are placed on the top and lowest compatible rows.
Printer
PLA uses no global scale correction. Default hook width is 3.7 mm with a 4.8 mm section. Confirm final fit with the gauge.
5 perimeters, 0.2 mm layers. Enable support beneath the hooks.
Shape
Optional weight reduction. The 45° diamond openings are intended to print without wall supports; the back, bottom, dividers, and hooks remain solid. Material use drops, but print time may not decrease with every slicer setup.Generation stays on your device; dimensions are not sent. Do not use for food contact, heavy loads, or anything involving the safety of people or animals.
Use and safety
STL and STEP files you create may be used personally or commercially. Test with light items first and never use the result where people or animals depend on it for safety.
