MAIN PURPOSE: Cut fingernails with one hand
Drop a standard clipper into the channel with its jaws over the front notch: slip a fingertip under the jaws and press the lever with your palm or wrist. The grip feet keep the board still, so nails can be cut with one working hand.

Fix the clipper with a dab of putty adhesive. Prints as shown on its floor, no supports.
MAIN PURPOSE: Show drawer contents with a picture
Slide a photo of what is inside into the grooved frame and stick it on the drawer front: a picture of socks or cutlery is easier to read than a word, so people living with dementia find things themselves. Takes credit-card size prints.

Fix with two small screws or a strip of foam tape. Prints as shown on its floor, no supports.
MAIN PURPOSE: Dry a washed CPAP hose without kinks
Hook it over the shower rail and drape the washed CPAP hose over the wide saddle: both ends hang down, the water drains out of the full length, and the 35 mm radius never kinks the tube the way a tap or a towel hook does.

Print as it comes (profile on the bed) in PETG.
MAIN PURPOSE: Watch a phone at eye level on a plane
Slide the thin tongue into the gap above the stowed tray table and stand the phone in the lipped cradle: films play at eye level without holding the phone or folding the tray down, and the whole clip lives in a jacket pocket.

MAIN PURPOSE: Stop backpack zips being opened in crowds
Hook the two zip pulls of a backpack pocket into the narrowed throats of this S link: the pocket can no longer be slid open quietly in a crowd, but your own fingers unhook it in a second.

MAIN PURPOSE: Hang a second bag on a rolling suitcase
The upper hook clamps over the extended telescopic handle and the deep lower hook takes the strap of a tote or laptop bag: the bag rides on the suitcase instead of slipping off your shoulder through the airport.

MAIN PURPOSE: Carry sunglasses on a backpack strap
The spring U slides onto a shoulder strap and the narrow slot behind it holds one arm of a pair of glasses: sunglasses ride on your chest, ready to put on, instead of being crushed in a pocket.

MAIN PURPOSE: Close the light gap between hotel curtains
Pinch the two overlapping edges of hotel curtains together with this hairpin spring: the strip of street light or early sun that always gets through the middle is gone, and you sleep in proper darkness.

MAIN PURPOSE: Keep tall boots upright and uncreased
Roll the flexible sheet into a tube, hook the two edge slots into each other and push it into the boot shaft: it springs out against the leather and keeps tall boots upright, so they never flop over and crease at the ankle.

MAIN PURPOSE: Zip up a back-fastening dress alone
Clip the small hook into the zip pull at the bottom of a back-fastening dress, take the ribbon over your shoulder and pull: the zip runs up to the neck without a second pair of hands. Unhook it with one twist.
