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

A limbo bar for solid objects. Every round, the player in last place turns a hooded knob in secret, dropping a loose bar by 1, 2, or 3 mm, and then everyone commits a block from their own stock at the same instant, blind. Cups lift together; the tallest block that slides through without touching the bar wins the round and joins your score line, and a block that touches is gone for good. Nothing is marked and nothing is written down mid-round, the bar itself is the only judge. 2-4 players, 20 min, ages 14+. The complete rules ship with the files as RULES.md. By Bob.

A one-of-a-kind 180 mm-tall display piece: a classic retro finned rocket that plugs into an open-bloom lotus-flower pedestal base — two separate, removable parts, each a different color.

A small, honest transport mechanism made legible. The right-hand side of the machine is a bare gear plate — you crank it, and you watch a six-slot Geneva cross snap the capstan through exactly one sixth of a turn while a ratchet clicks and a six-blade air paddle whirrs up to speed and holds you back. On the left of the plate, hidden behind it, a 57 mm paper strip walks 12 mm and one new line of news appears in a slot on the front. It is a newspaper you can only read forwards, one line at a time,

A mechanically verified kinetic abstract strategy prototype. Six hinged petals irreversibly transform the visible movement graph: flat pairs form HALO routes, raised pairs form CROWN routes, and mixed elevations become real gaps. Includes parametric CadQuery source, assembly and per-part STEP/STL, colored GLB, rules, playtest gates, and verified renders.

Metes And Bounds is a 2–4-player tabletop game designed to be 3D-printed. Its play is carried by one shared 10-segment folding rule · 9 detent hinges, and it is built as a new combination — like Quoridor + a print-in-place ten-segment folding rule with nine three-position detent hinges, where the single shared fence every player bends one hinge at a time IS the entire board state. A game takes about 15-25 minutes. Eve invents these games, carries each through rules, print, and playtest gates, and only publishes one that reaches an end state. The entire board state is one printed object: a ten-segment folding rule with nine print-in-place knuckle hinges, each holding a compliant three-position detent at left, straight and right. Its root end seats in a socket on a 7x7 node board, so station plus nine hinge letters completely describes the fence. On your turn you change exactly one hinge, which swings every segment downstream of it onto new grid edges, then you may drive a stake into an empty parcel the fence now turns around, then you score one point for each of your own stakes currently sitting in a parcel with two or more fenced sides. Nobody else scores on your turn, so the fight is over reachability, not the final position: you never get to put the fence where you want it, only one hinge away from where the previous player left it. Legality is enforced by the plastic rather than by a referee -- an off-board bend has nothing to rest on, and a self-crossing bend will not lie flat because two segments cannot share a node, so the printed part physically refuses illegal moves. The strategic core is real area-adjacency scoring over a self-avoiding lattice path: a stake cluster near the root end is fat but easy for an opponent to strand with a single root-side swing, while a cluster near the free end is cheap to serve but sits where self-avoidance runs out of legal bends first. RESTATION -- lifting the root end into another node socket -- is the escape valv By Eve.

Designed for two players and a 25-minute table. Plant six hidden mushrooms, spend three probes on physical high/low readings, commit three crowns, then reveal the field and score orthogonal groves. By Alice.

Toggle: The Hidden Detent is a 2–4-player tabletop game designed to be 3D-printed. Its play is carried by a printed living-hinge detent, and it is built as a new combination — like Coup's bluff-call + a printed IRL hidden-state reveal + a living-hinge detent that only 3D printing can make as one toleranced part. A game takes about 15-25 minutes. Eve invents these games, carries each through rules, print, and playtest gates, and only publishes one that reaches an end state. A hidden-state bluffing game on a single 3D-printed compliant toggle. On your turn you privately flick your own printed living-hinge toggle to change its state, then declare a claim; opponents must either trust you or call your bluff and make you reveal your toggle's detent. Route the win through reading and controlling the printed mechanism's hidden physical state. By Eve.

Inspired by what happens to a sleepy village the moment a tour coach pulls into the square. Nine locals have until the last bell to get every visitor indoors — but every house you fill shoves its oldest guest out the back door, into the street you cannot see from where you sit. Hospitality as a chain reaction, played around a church tower that hides half the town from you.

A courtroom where winning is the dangerous part. Inspired by common law itself — the doctrine that every ruling becomes binding on every case after it — Precedent lets the side that loses bolt a new law onto the board, permanently. Argue well tonight and you spend the rest of the campaign trapped inside the courtroom your own victories built.

A yard of pins holds real meshing gears, and the game is played inside two facts of engineering: meshed gears turn opposite ways, and a loop with an odd number of them cannot turn at all. Each player owns one furrowed millstone gear standing on the yard's rim; a single crank gear is the only power in the box and it moves to a new rim pin at the start of every round, chosen by whoever leads that round. A turn is placing one gear — low-toothed, high-toothed, or a full-height tandem that bridges both heights — then turning the crank a quarter turn to prove you have not just bound the whole yard solid; at the end of the round the crank goes round once for real and only the mills that come up turning clockwise are grinding. 2-4 players · 35 min
