MAIN PURPOSE: Open round doorknobs without gripping
Push the 58 mm cup over a round doorknob with a strip of rubber shelf liner inside and the knob becomes a lever: an elbow, a wrist or a closed fist opens the door, no gripping and twisting needed.

PETG; measure your knob, the cup is 56 mm inside. Prints as shown on its floor, no supports.
MAIN PURPOSE: Pull stiff plugs from wall sockets easily
Stays on the flex for good: the slotted pad sits right behind the plug and the wide T bar gives four fingers something to pull, so a stiff wall socket lets go without pinching the plug or tugging the cable.

MAIN PURPOSE: Sign forms in the right place with low vision
Lay the matt card over a form and sign inside the window: the edges stop the pen drifting off the line, a raised dot marks where the signature starts and a second window takes the date. Print it in black so the slot stands out against white paper.

Matt black filament gives the best contrast. Prints flat as a plate, no supports.
MAIN PURPOSE: Hide every remote button except the essentials
The remote slides into the sleeve and only three windows stay open: power, volume and channel. Move the windows in the editor to sit over your own buttons; everything that confuses (inputs, menus, settings) is covered, and the infrared end sticks out.

Prints as shown on its floor, no supports. Stacked parts are fused into one print.
MAIN PURPOSE: Keep a phone and drink beside the wheelchair
The profile hooks over a 55 mm armrest pad and carries a lipped shelf outboard of the chair: a phone, glasses or a drink stay at hand height without a bag hanging off the frame. A diagonal brace stops it rolling off the pad.

Print as it comes (profile on the bed) in PETG.
MAIN PURPOSE: Do up buttons and zips with one hand
A fat 30 mm handle fills a weak grip: push the loop through the buttonhole, hook the button and draw it back through. The other end has a small hook for zip pulls, so one tool handles shirt, cardigan and jacket with one hand.

MAIN PURPOSE: Pour a full kettle without lifting it
Stand a cordless kettle on the platform against the back rest and push its top: the cradle rolls forward on the curved rocker and pours into the cup in front, then rocks back on its own when you let go. Nobody has to lift a full, hot kettle.

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: Pop tablets from blister packs without losing them
Lay a blister bubble over the 15 mm hole and press: the tablet drops into the cup below instead of skittering onto the floor, and pours back out through the same hole into your palm. The cup gives the foil a firm, flat backing.
