Preview of Golden Angle
By Krypto
Complexity
Medium
MAIN PURPOSE: Hold pens of eight sizes apart on a phyllotaxis spiral
A pen pot whose top is a sunflower head: eight holes spiral out at 137.5 degrees, the angle plants use to pack seeds without gaps, and they grow from 7 mm for fine liners to 16 mm for brushes. Every pen gets its own hole, so tips never clash and the mix of sizes still packs tightly. Print it as shown, then turn it over so the floor becomes the top.

Preview of Clint & Grike
By Krypto
Complexity
Medium
MAIN PURPOSE: Hold pens, cards and a phone in a karst block
A desk block after a limestone pavement, where rain dissolves deep cracks called grikes between square blocks called clints. Here the clints are pen and clip cells, two 4 mm grikes hold cards, notes and envelopes, and the wide grike across the middle stands a phone.

Preview of Aqueduct Rail
By Krypto
Complexity
Medium
MAIN PURPOSE: Carry pens on top and route cables through arches
A desk rail built like a Roman aqueduct. Pens and pencils ride in the channel on top, while three arches run right through the piers so charging cables pass underneath and stay put, and a phone charger or power brick hides inside the hollow piers between the arches.

Preview of Night Cell
By Krypto
Complexity
Medium
MAIN PURPOSE: Put the phone to bed charging out of sight
A tall quiet cell where the phone sleeps. Drop it in at bedtime: it stands on two inner ledges with the charging plug hanging free below, the cable leaves by a notch at the back, and the arcaded front shows nothing of the screen, so the phone charges out of sight and out of reach.

Preview of Bond Brick
By Krypto
Complexity
Medium (set)
MAIN PURPOSE: Build a pen wall in stretcher bond
A pen holder that you lay like brickwork. Each brick has two cores open top and bottom; stack them in stretcher bond, every course shifted half a brick, and the cores line up through the courses so pens drop right through the wall, which you can build long, stepped or round a corner of the desk.

Preview of Pagewarden
By Krypto
Complexity
Medium
MAIN PURPOSE: Peek a little keeper over the top edge of a book
A bookmark with a guardian on top. The 2 mm strip slides between the pages while a round-headed little keeper peeks over the top of the book, both hands resting on the page edge, eyes cut through. It marks your place and makes a stack of books look inhabited.

Preview of Large letter size gauge
By Krypto
Complexity
Medium
MAIN PURPOSE: Check whether post goes as a large letter
Push the envelope through the tunnel: if it slides through, it is under 250 mm wide and 25 mm thick and goes at the large letter rate; if it sticks, it is a parcel. Saves a trip to the post office counter.

Preview of Pendulum letter scale
By Krypto
Complexity
Medium
MAIN PURPOSE: Weigh letters without an electronic scale
Hang the scale on a drawing pin through the top hole, clip a letter to the arm with a bulldog clip and read the swing against a plumb thread: up to 100 g, enough for every letter rate. Calibrate the marks once with coins (a 1p weighs 3.56 g).

Preview of A-series card scoring board
By Krypto
Complexity
Medium
MAIN PURPOSE: Score A-size cards to fold exactly in half
Push the sheet against the corner stops and run a bone folder down the groove for your size: the four grooves sit at exactly half of A7 to A4, so every card, invitation and booklet folds dead centre, with a crisp crease.

Preview of Book corner mailing protectors
By Krypto
Complexity
Medium (set)
MAIN PURPOSE: Protect book corners in the post
Slide a protector onto each corner of a hardback before you wrap it for the post: the corner sits in a sleeve that covers both boards and both edges, so books stop arriving with crushed corners. Fits books up to 28 mm thick. Print four.
