MAIN PURPOSE: Fold ribbon cable into clean right-angle turns
Lay a 40-way ribbon cable in the tray and fold it back over one of the 45 degree end walls: the crease comes out at exactly 45 degrees, so the cable turns a clean right angle inside a case instead of twisting or bunching against the lid.

MAIN PURPOSE: Keep a chuck key on its machine
Snaps onto the power cord of a drill press or lathe and holds the chuck key by its shank beside the plug: you have to take the key out to unplug the machine, and it is always within reach when you need it.

MAIN PURPOSE: Fit Gridfinity magnets with matching polarity
Stack a column of 6 x 2 mm magnets in the tube: they line up north to south by themselves, so the bottom one always shows the same pole. Press the tube over a bin's magnet pocket, push the stack down with a pencil and slide away, and every bin in the drawer gets the same polarity.

Check the 6 mm bore holds magnets with light friction. Prints as shown on its floor, no supports.
MAIN PURPOSE: Plan Gridfinity grids and bin heights
Lay the long arm in a drawer to count how many 42 mm units fit across it and how much gap is left, then stand the short arm up against the drawer above to see the tallest bin, in 7 mm height units, that will still close. Plan a whole drawer before printing a single bin.

MAIN PURPOSE: Hang Gridfinity bins on a shelf edge
The back hook drops over the edge of an 18 mm shelf or batten; a bin's back wall slides into the front hook, stacking lip and all. Two hangers turn any Gridfinity bin into a wall or shelf-edge bin and back again, without a dedicated wall plate.

Print two per bin in PETG. Prints as shown on its outline, no supports.
MAIN PURPOSE: Lock a Gridfinity baseplate tight in a drawer
Drawers are never an exact number of 42 mm units. Push a pair of these tapered wedges between the baseplate and the drawer side, from opposite ends: they close any gap from 4 to 16 mm and lock the grid, so the bins no longer shift when the drawer slams.

MAIN PURPOSE: Train climbing finger strength by lifting a weight
Girth-hitch a sling round the neck under the T bar, clip on a kettlebell or a bag of weight and lift it off the floor with your fingertips in the 20 mm or the 15 mm incut slot: climbers can train finger strength anywhere, with no hangboard and no door frame to drill.

MAIN PURPOSE: Stop weight plates sliding off a barbell
A clip-on collar for a 50 mm Olympic sleeve: squeeze the two ears together, the ring opens, slide it against the plates and let go, and the 25 mm deep ring grips the sleeve so the plates cannot creep out during a set.

MAIN PURPOSE: Attach a race number without pinning the shirt
Four magnet pairs replace the safety pins on a race number: one button inside the shirt, one outside the bib, and they snap together through both layers. No holes in a technical shirt, and the number stays flat at any pace.

MAIN PURPOSE: Draw straight alignment lines on golf balls
Drop a ball into the box and run a fine marker down the front slot, then the back slot: both slots lie on one great circle, so the two strokes join into a long straight putting line. Turn the ball, repeat, and every line is true.
