Toys & mechanisms / Mechanical
Climbing Monkey — Classic Rope-Climbing Pull Toy
Pull the two beads alternately and the monkey ratchets up the cords toward his banana — let go and he stays put, slacken both cords and he slides back down. No springs, no glue, no mechanism to assemble: pure capstan friction through 45° paw channels. 3 printed parts + string. Prints flat, no supports. Kid-safe: Ø33 mm beads pass the choke gauge.

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.

Jonah Whale - Press the Blowhole to Open the Jaw
A print-in-place whale toy. Press its blowhole and the jaw drops open to reveal a tiny diver.
Toys & mechanisms / Mechanical
Marble Run — Print-in-Place Roman-Greek Track
One-shot print-in-place marble run with a 3-pin plinko mid-section, sloped chute finish, and integrated Roman column supports. Greek-key meander engravings on all outer walls. Ships with a standalone start-hopper accessory + start/finish flag pair.
Toys & mechanisms / Mechanical
Pop-Up Toaster — Toy with a REAL Spring-Launched Pop
A pretend-play toaster that actually works: press the side lever DOWN and it clicks down and latches; push the side EJECT buttons and POP — both toast slices spring up out of the slots. Real printed coil springs and a self-engaging sear latch, just like a 1950s toaster. No glue, snap-together, kid-safe energy budget.
Toys & mechanisms / Mechanical
Pythagorean Cup — Greedy Cup / Cup of Justice (parametric)
Drink from it normally and it works like any cup; fill it past the 'greedy line' and the entire contents siphon out the bottom. Attributed to Pythagoras (~6th c. BC) — a working hidden-siphon trick cup. Parametric SCAD: change cup_d / cup_h to resize.
Toys & mechanisms / Mechanical
Tank Shooter — chunky display tank, print-in-place tracks
A chunky stylised T-34-ish display tank: articulated print-in-place link tracks that wrap the road wheels, a rotating turret, and a cosmetic gun with a friction-seated dummy shell. No glue, no supports, no hardware, AMS multi-colour. A DISPLAY model — the tracks don't drive and the gun doesn't fire.
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.
Toys & mechanisms / Mechanical
Lazy-Tongs Snapping Dragon — extending scissor grabber
A lazy-tongs scissor reacher themed as a dragon: squeeze the tail and the neck telescopes out while the head snaps shut — one motion, one moving mechanism.
Toys & mechanisms / Mechanical
Squeeze Breeze — Trigger-Spun Fan Toy (no batteries, mechanical novelty)
A no-batteries mechanical novelty: squeeze the finger trigger and a multi-blade propeller on a flywheel spins up through a one-way ratchet, then coasts between squeezes. A satisfying hand-powered fidget that LOOKS like a hand fan. NOTE: it's a toy — the spinning blades move only a faint wisp of air, not a real cooling breeze. Multi-part, every part prints flat and supportless. Fully parametric OpenSCAD.
