Updated December 2025 - Added OpenSCAD generator to make custom sizes
Use walls and corners to hold irregular shaped items in place on Toolgrid boards. The tee is great when multiple items are close together.
Holes are provided in the bottom for locating pins. I use 1/8" x ½" split roll pins. The pins fit snugly in the walls, but allow for a small amount of movement on the grid.
The holes for all the screws are large enough for a #10 pan head screw (5mm hole, 10mm head clearance).
Everything prints without supports.
The FreeCAD model file is provided in case you wish to make adjustments. Most dimensions are in a VarSet.
The OpenSCAD customizer is now the recommended method of creating custom sizes. This is especially needed for the U shape.
