Screw these into the sides of drawers so you can slot a piece of wood (or 3D printed wall) in-between to make a divider.

The .STL files have a design for an 8 mm thick board, or a 5.6 mm thick board. The 5.6 mm design is slightly shorter.

If you want a custom thickness, you can easily modify the .SLDPRT files by changing the variable "nominal_width", which should be equal to the exact thickness of the board you're using (padding will be added automatically).

The screws are #8 1/2 in with a flat head and 82 degree countersink.
