MAIN PURPOSE: Sew buttons on with a strong thread shank
Lay the fork across a coat button between its holes and sew over the two tines; slide it out, wind the thread round the slack and you have a proper thread shank, so buttons on thick fabric stop pulling loose and tearing off.

MAIN PURPOSE: Direct radiator heat into the room
Sits on top of a 100 mm double-panel radiator, gripping both panels: the shelf and the forward lip turn the rising warm air into the room instead of up behind the curtains or onto a cold window sill. Print several and butt them along the radiator.

MAIN PURPOSE: Press air out of a bokashi compost bucket
After each layer of scraps and bran, push this plate down hard in the bokashi bucket to squeeze out the air the fermentation hates; six ribs keep the 220 mm plate stiff and give fingers a grip, and it stays on top as the cover layer.

Check the inner diameter of your bucket first. Prints as shown on its floor, no supports.
MAIN PURPOSE: Measure shower flow to find water savings
Hold it under the shower for exactly six seconds and read the level: the marks give the flow in litres per minute. Anything over 9 means an aerated shower head would cut hot water, and the energy to heat it, straight away.

MAIN PURPOSE: Stop charger cables fraying at the plug
Snap it over a charger or headphone cable where it starts to fray at the plug: the 30 mm sleeve stops the sharp bend that breaks the wires, so a tiny repair keeps the cable out of the e-waste bin for years.

MAIN PURPOSE: Stop an interior door from latching
Slide the U over the edge of a 40 mm interior door where the latch is: the bolt is held in, so the door closes quietly for a sleeping baby, cannot shut a child or a pet in, and swings open with a nudge while you carry boxes through.

MAIN PURPOSE: Keep smart bulbs powered at the wall
Screws over a standard 86 mm light switch through the plate's own screw holes and hides the rocker, so nobody switches smart bulbs off at the wall and leaves them unreachable from the app. Two screws out and it is a normal switch again.

MAIN PURPOSE: Keep blind cords out of children's reach
Fix this T-cleat at least 1.5 m up the window frame and wind the blind cord round its two horns in a figure of eight: the loops stay out of a child's reach, the safety rule for corded blinds and curtains. Drill two 3.5 mm holes through the base for screws.

MAIN PURPOSE: Protect an outside tap from freezing
Slip it over an outside tap before the first frost, open side to the wall, stuff it with bubble wrap or wool and hold it with a bungee through the side holes: the tap stays above freezing, and the notch clears a pipe that runs down the wall.

MAIN PURPOSE: Start holes in glazed tiles without skidding
Stick it on a glazed tile with double-sided tape, fill the inner ring with water and drill through the centre hole: the bit cannot skate across the glaze, and the water runs down to keep diamond and tile bits cool so they cut instead of burning.
