Preview of Water-molecule desk tidy
By Krypto
Complexity
Advanced
MAIN PURPOSE: Sort pens and clips in an H2O molecule
A desk tidy built as a water molecule: one large oxygen cup for pens, with two smaller hydrogen cups bonded at a wide angle for clips and erasers. H2O is moulded on the front. A science-teacher gift that earns its place on the desk.

Preview of Mushroom spore-print box
By Krypto
Complexity
Multi-part assembly
MAIN PURPOSE: Take spore prints of four mushroom caps undisturbed
A box for foragers and mycology fans to take spore prints. Lay a cap gills-down on paper in each of the four bays and close the lid overnight. Draughts can't smudge the prints, and spores from one cap can't drift onto the next, so the colours you get back are true for identification.

Preview of Meridiana
By Krypto
Complexity
Medium
MAIN PURPOSE: Mark solar noon and the season with a sun spot
A cathedral meridian line in miniature for a sunny windowsill. Turn the tall wall due south: at solar noon its pinhole throws a spot of sunlight onto the floor rib, and where the spot lands on the engraved marks tells the season, from the high June sun near the wall to the low autumn sun at the back.

Preview of FitzRoy Tower
By Krypto
Complexity
Medium
MAIN PURPOSE: House and read a storm glass weather vial
A tower for a 25 mm Victorian storm glass vial. The vial stands inside behind two tall windows, so light passes through and the crystals read clearly, and the side wall carries the old reading key: clear for fair, cloudy for rain, stars for cold and snow.

Preview of Fulcrum Stand
By Krypto
Complexity
Simple
MAIN PURPOSE: Hold a balance beam on a knife-edge pivot
The pivot for a desk lever lab: a lambda frame of 9 mm legs rising to a rounded knife tip, standing on two foot bars. The Fulcrum Beam rests its arch on the tip, so the pivot sits above the beam and it swings and settles like a real balance. The tip also carries the Moonbalance crescent.

Preview of Fulcrum Beam
By Krypto
Complexity
Simple
MAIN PURPOSE: Show balancing moments with coins and clips
A 249 mm balance beam whose central bridge arch sits on the Fulcrum Stand tip, 18 mm above the beam line so it always swings back level. Eight V notches at matched distances hold paper clips loaded with coins: put two coins at 32 mm and one at 64 mm on the other side and watch the moments cancel.

Preview of Voussoir Wedge
By Krypto
Complexity
Simple
MAIN PURPOSE: Build a self-supporting arch from nine blocks
One stone of a self-supporting arch: print nine of these 20 degree wedges, lay them over the Voussoir Centring, drop in the last as the keystone and pull the centring out. Nothing holds the arch but compression, exactly as in a Roman bridge. The hollow side faces the back.

By Krypto
Complexity
Simple
MAIN PURPOSE: Support arch blocks while the arch is built
The temporary form an arch is built on: a solid semicircular rib with foot pads, sized so nine Voussoir Wedges sit on it. Stand it up, lay the wedges from both ends, set the keystone, then slide the centring out sideways and watch the arch carry itself.

Preview of Rekenrek Frame
By Krypto
Complexity
Medium
MAIN PURPOSE: Teach counting in fives and tens with beads
A 20-bead rekenrek, the Dutch counting rack that teaches number sense in fives and tens: two rods run the length of a 260 mm tray, ten beads on each, five red and five white. Children slide groups across to see 7 as 5 and 2 at a glance. Uses 4 mm rods or bamboo skewers.

Preview of Automaton Stage
By Krypto
Complexity
Medium
MAIN PURPOSE: Turn a crank to make cam-driven figures move
The frame of a cam automaton: push an 8 mm dowel through the side holes as a camshaft, thread on three Helix Spindle discs printed at half size, and drop 6 mm dowels through the top holes so they ride on the cams. Turn the crank and the rods bob in sequence, ready to carry paper or printed figures.
