Preview of Jigsaw-piece link trays
By Krypto
Complexity
Simple (set)
MAIN PURPOSE: Print several puzzle-piece trays that lock together into one
A desk tray in the shape of a jigsaw piece, with two tabs and two blanks. Print four and they lock into a square, print nine and you have a 3x3 organiser, and pull one out to take it to another desk. It is a modular system that is also a puzzle.

Preview of Family chore turntable
By Krypto
Complexity
Multi-part assembly
MAIN PURPOSE: Rotate household chores between family members every week
No more arguing about whose turn it is. Each bay holds a family member's name token, and each side of the box names a chore: DISHES, BINS, PETS, TIDY. Every week, a quarter turn on the ball-bearing base moves everyone on to the next job. It is fair, visible and spun by the children themselves.

Preview of Swear jar
By Krypto
Complexity
Multi-part assembly
MAIN PURPOSE: Collect a coin for every swear word through a swinging flap
The family swear jar, with a bin-style swing flap that swallows each fine with a satisfying clack. SWEAR JAR is raised on the front and PAY UP on the side. Spend the takings on a takeaway everyone shares.

Preview of Tilt-to-choose spice shaker
By Krypto
Complexity
Advanced
MAIN PURPOSE: Sprinkle or pour from one shaker by tilting it one way or the other
One spice shaker with two behaviours. Six small holes are grouped on one side of the cap and two large ones on the other: tilt towards SHAKE and the spice sprinkles, tilt towards POUR and it flows. There is no lid to turn and no second jar, so it suits chilli flakes, herbs and sesame seeds.

Preview of Box-breathing finger tracer
By Krypto
Complexity
Simple
MAIN PURPOSE: Trace a square track with a fingertip to pace box breathing
Box breathing (in for four, hold for four, out for four, hold for four) calms nerves before exams and meetings, but counting is hard when you are anxious. This palm-sized tray gives your fingertip a square channel to trace, one side per breath stage, with IN, HOLD, OUT and HOLD on each side. Your finger keeps the rhythm so your head doesn't have to.

Preview of Pet-rock adoption crate
By Krypto
Complexity
Multi-part assembly
MAIN PURPOSE: Give a found pebble a home, a bed and a name
A shipping crate for the lowest-maintenance pet there is. Breathing holes run along both sides (the rock does not need them, which is the joke), a low bed rail keeps it from rolling about, and PET ROCK is stencilled on the front like freight. Children find a pebble on a walk, paint a face on it and give it a name. It also makes a good office secret-Santa gift.

Preview of Penrose-stairs organiser
By Krypto
Complexity
Advanced
MAIN PURPOSE: Sort desk bits in boxes that step round like the endless staircase
Four long boxes pinwheel round a central well, each one a step taller than the last, like the Penrose stairs in Escher's Ascending and Descending. Clips go in the lowest, pens in the tallest, and the centre takes the phone. It is a useful organiser that looks as though it climbs forever.

Preview of Saguaro-rib cachepot
By Krypto
Complexity
Simple
MAIN PURPOSE: Shade a potted plant with ribs that cast their own shadows, like a cactus
Saguaro cacti survive desert sun partly because their deep pleats shade their own skin. This cachepot borrows the trick: deep vertical ribs round the outside mean much of the surface is always in shadow, so the nursery pot inside stays cooler on a hot balcony. It also makes a striking sculptural pot.

Preview of Ticket-stub keepsake box
By Krypto
Complexity
Multi-part assembly
MAIN PURPOSE: File concert, theatre and match ticket stubs by year
Ticket stubs are the best diary of nights out, and they end up crumpled in drawers. This box files them upright in four rows, one per year or one per venue, so you can flip through them like records. SHOWS is raised on the lid.

Preview of Spin-art paint spinner
By Krypto
Complexity
Multi-part assembly
MAIN PURPOSE: Spin a card on a turntable while dripping paint for spin art
Spin art as at the fairground: a square of card spins on a ball-bearing turntable while children drip paint on it, and the tall wall round the edge catches the spray so the kitchen doesn't get painted too. No motor or batteries, just a good push.
