New toys invented everyday.

A chunky mint axolotl-dragon with coral gills, an articulated tail and three interchangeable expressions.

A grey robot duck with a yellow bill, purple details and a side winding knob. A replaceable silicone cord stores the twist that drives its small wheels.

A palm-size wind-up walker. Twist the knob at the back to wind it up, set it down, and it trots forward on four legs with a smooth, life-like gait - no batteries, no motors. The rubber band inside drives two crankshafts that swing the legs in turn, so it keeps its balance step after step. Every part is 3D printed.

A fun shooting game for basketball lovers. Place the ball on the lever and shoot it. Whoever scores the most, win.

A complete New York chess set uniting landmark towers, rooftop water tanks and a sculpted route through five city communities. Warm limestone and midnight blue-green armies share an architectural language of stepped stone plinths and recessed detail.

A palm-sized pearl jellyfish with soft pink and blue accents, eight beaded tentacles and four flowing ribbons. Its wind-up mechanism and pressable bell are designed to create a gentle swimming pulse.

Nine mountain-wall modules. Two watchtowers. One continuous route. Choose one of fourteen challenge setups, place its clues, then lift, quarter-turn and place the remaining pieces. Connect G1 to G2 through all nine modules, matching both direction and height at every seam. Start with the illustrated two-piece tutorial, then explore the full 3 × 3 puzzle. Includes nine modules, one numbered cradle with an engraved 3 × 3 grid and north marker, editable Python, colored STEP files and a 13-page guide. Assembled size: 174 × 182 × 63 mm, including the north tab. Digital prototype; physical fit and play have not been tested. The downloadable STEP preserves the sandstone, moss, brick-red and teal face colors shown in the covers. The current web viewer simplifies each solid to one color.

A six-legged yellow and black mecha spider: long faceted hull with swept antenna blades, tall shin guards on steel-look claws and pale cable loops, assembled from 16 printed part roles.

A four-legged Theo Jansen walker, geared and dressed as a horse - the mechanism stays in the open and becomes the animal's body.

A crank-counterbalanced beam pumping unit, modelled from fourteen studio views and driven by an Adafruit 2941 gearmotor through an 8:1 worm pair into a crank-rocker four-bar: about 14 strokes a minute, 54.6 mm of polished-rod travel. Authored full size in real millimetres and reduced by one number, SCALE = 1/40 - 156.6 mm tall, 139.7 mm long, on a 220 x 220 x 250 mm bed. 21 printed parts, 30 pieces, split along the machine's own construction seams. Not verified as finished: the silhouette likeness gate scores mean IoU 0.655 against its 0.90 floor across four reference views, and the print gates have not been run, so printability is unverified. Layout, bed fit, the local fit audit, spec numbers and format, the landmark ledger, mounts, power, motion and a 47-request topology batch all passed.

A 390 mm-wingspan F-14D Tomcat that sits on its own landing gear like a ramp-parked jet. Sixteen colour-separated printed parts - gloss-black airframe and spine deck, pale-khaki tandem canopy, red-tipped twin tails, red intake frames and nose strut, orange afterburner nozzles and a full tricycle gear - assemble into a spread-wing display pose. 390 x 388 x 117 mm (about 15.4 x 15.3 x 4.6 in).

An original, 3D-printed family strategy board game rooted in the 24 solar terms (二十四节气, UNESCO intangible heritage) and the Wuxing five-element cycle: a Ø250 mm circular walnut-tone board with a click-detented rotating celadon wheel at its center.

Flick soccer / sling soccer game set for 2

A pocket bowling toy: a lane tray that ramps into a flick-launch pad and doubles as nested storage, six molded pins in a 3-2-1 triangle, and one flick disc — flick the disc off the ramp to send it down the lane into the pins.

A hand-cranked walking machine on fifteen Jansen-linkage legs. Turn the knob and the crankshaft sets each leg 45° behind the last, so the feet take turns on the ground and the body glides almost level. Rebuilt at 1:4 from Zolko's CC0 FreeCAD Sandwalker, after Theo Jansen's beach walkers, as a printable kit: 17 printed part types, two 6 × 400 mm steel axles and eight ISO 2338 dowel pins; 528 × 430 × 326 mm assembled.

A crouching skeletal dragon with a toothed skull, swept horns, open ribs and finger-bone wings above a fractured stone base.

A push-along automaton: a carousel Pegasus, carved, gilded and jewelled like a fairground jumper, flies on a twisted gold pole above a rolling plinth. Push it along the table and every turn of the wheels beats its wings once. 27 printed parts and six O-ring tyres.

A spiral galaxy you can spin. Four sweeping black arms carry chains of brass gears that shrink toward a glowing orange core. Give the rim one push and the whole galaxy turns on its slim stem: a hidden fixed sun gear sets every gear spinning at its own speed, each one reversing the next, while the core wheel turns the opposite way. No motor, no batteries, just gears.

A 3D-printable 2030 sf chess set (f).

Jungle Chess played with the solar system. Every piece is a planet, and a planet's size on the board is the fifth root of its real measured diameter, so rank is something you can see rather than learn: Mercury is the smallest world in play and Jupiter the largest, and the traditional rules are followed exactly as written. The two armies are the same sixteen worlds facing each other, told apart because each pair is a mirror of itself -- five of the eight by the lean of the globe at the planet's own true axial tilt, and Mercury, Venus and Jupiter, whose tilts are too small to show one, by the map instead. A star stands at each end with two flames bursting off the board edge, and they are the only raised flames on the board: the three trap cells around each star are flat tiles with a sunken sixteen-rayed star cut into them, and a world caught on one drops three millimetres out of the light and its rank counts for nothing.

A stock-market desk seesaw: a green Wall Street bull and a red grizzly ride an open black beam over an exposed brass gear train. Tilt the beam and the gears turn the rising animal's two-sided face block 180°: the bull flips to a big grin, the bear to crying with blue tears. At level both faces are neutral.

A print-in-place flexi axolotl in Mintfin's colours: an ice-blue segmented body that wiggles straight off the bed, coral leaf gills and a five-leaf fan tail, three charcoal horns glued into the crown, and a removable happy or sad face that presses onto a key under the eyes. Five multi-colour prints for a 220 mm bed. Body and head surfaces are Printyboy's Flexi Axolotl, carried from the designer's meshes.

A complete 3D-printable Xiangqi (Chinese Chess) set, featuring: • 1 Chessboard: Designed with an elevated border frame and 2 integrated sliding drawers (one for each player's color). • 32 Circular Disc Pieces: Engraved with traditional Chinese characters.

A gimbal-mounted tilting dish. Every colony tower you plant physically unbalances the world; marbles roll downhill into someone's territory.

Precision Laser-Engraved Orbital Base with 10 Magnetic Planet Modules (Sun, 8 Planets & Pluto).

A full chess set of little robots, rebuilt from the twelve reference renders in `ref/`: a **terracotta side** (terracotta, cream trim, cream sunburst) and a **cream side** (cream, dark-green trim, green rosette). Both sides use one shape per piece type, so the set plays like any chess set. Sizes follow the FIDE standard: king 95 mm, queen 85, bishop 70, knight 60, rook 55, pawn 50. The board has 54 mm squares, 432 mm across, and prints as four tiles joined by eight keys. The cream side plays White.

A 3D-printable alignment themed san francisco chess set (f).

A complete Double-6 domino set — 28 tiles (48 x 24 x 8 mm) with raised embossed pips — stored in a fitted two-row tray with a slip-fit lid.

A Kriegsmarine Type VIIC, printed as two PLA pieces that peg the AI service at midship.

A desk automaton: a soaring red kite that beats its wings on a hand crank, or on a TT motor through a 17/39 gear pair. Seven print-in-place panels in cocoa brown over a black geared motor box, 284 mm wingtip to wingtip, the bird authored from red kite photographs. Parametric STEP source; print gates not run, so printability is unverified.
