Make a toothbrush holder

Start from a blank workpiece

Stack three wooden rings on a solid base

Make a toothbrush cup from plywood rings glued onto a wooden base. Wood glue joins the layers; this version needs no screws or separate hardware. In Easel, start with ¾-inch plywood and draw four circles, each 2¾ inches across. Leave one circle solid for the base. Put a centered 2-inch circle inside each of the other three to form the rings. Set the outside edges to cut outside the shape and the openings to cut inside, all the way through the plywood.

After cutting, remove the tabs and circular offcuts, then sand the mating faces. Glue the three rings together with their openings aligned, and glue that stack onto the solid disk. Clamp until the glue cures. At the example thickness, the cup is 3 inches tall with a 2¼-inch-deep interior and a ⅜-inch wall. Measure your actual plywood and brush handles before resizing; the recording lays out these four parts rather than reproducing either maker's file.

Finish the inside and outside before bathroom use. This solid-bottom version is a holder, not a watertight drinking cup: let brush handles dry and wipe out any collected water. MakerSpace Zurich's original includes a different base with a narrow drainage slot.
