Biohazard Coasters — raised trefoil that lets go of a wet glass, plus caddy
Ø90 mm coaster set with the biohazard trefoil standing 0.8 mm proud of the drink face, so a cold wet glass rests on three lobes and never suctions to the floor. Two-colour AMS file with the six-island mark pre-welded into ONE part, a single-colour version, and a stacking caddy for four. No supports.

Wand Through the Wall — a Straight Wand Passes Through a Curved Slit
A dead-straight wand on a little turntable swings clean through two CURVED slits in a wall, twice per turn, without bending. The wand is skew to the axis, so it sweeps a hyperboloid; the wall cuts that in a hyperbola, and that is the slit. Four flat supportless parts, formula engraved on the base.

Toys & mechanisms / Mechanical
Desk Gyroscope — two-axis gimbal flywheel (a toy, not a tool)
A heavy-rim flywheel spinning in a two-axis gimbal on a pedestal — pull the string and the spin axis holds its direction while you tilt the base. A desk toy and physics demonstrator, nothing more.
