MAIN PURPOSE: Wear a locker or house key on the wrist
A flexible bracelet for the locker key: slip the open cuff over your wrist and hang the key ring on the tab, so the key stays on you in the pool, at the gym, on a run or on the beach instead of in a pocket you do not have. Print it in TPU so it springs round any wrist.

TPU, printed flat. Prints as shown on its outline, no supports.
MAIN PURPOSE: Hold a charging phone at a low socket
Unplug the phone charger, slip the slot in the back plate over its pins and plug it back in: the charger now holds the saddle to the wall and the phone rests in the pocket below with its cable looped in, instead of on the floor of a hotel room, airport or station with low sockets.

PETG; the plate is only 2.4 mm so the pins still seat fully. Prints as shown on its floor, no supports.
MAIN PURPOSE: Hold a phone or list on a shopping trolley
Snap it onto the handle of a supermarket trolley or basket and stand your phone or paper shopping list in the fork: the list stays in front of you at eye level and both hands stay free for the shelves. Fits handles 28 to 32 mm and phones up to 15 mm thick in a case.

Print it lying on its side (the profile flat on the bed) in PETG.
MAIN PURPOSE: Tap a transit card without taking it out
Slide the sleeve onto the shoulder strap of your backpack and push your transit or office pass into the front channel: at the ticket gate or door reader you tap your shoulder, through the 46 mm window, instead of digging through pockets. The card cannot slip out sideways and the strap slides in through the side gap.

PETG, printed standing on end so the channel is clean.
MAIN PURPOSE: Add a bedside shelf to a bunk or berth
Hook it over the guard rail of a bunk, sleeper train berth or hostel bed: the 70 mm shelf sits on the mattress side at pillow height and holds phone, glasses and earplugs within reach in the dark, instead of lost in the sheets. Fits rails up to 26 mm thick.

MAIN PURPOSE: Add a handle to a takeaway coffee cup
Slide the split ring up a paper takeaway cup until it wedges on the taper: the hot cup now has a proper handle, so you can carry it without a sleeve or burnt fingers, and it slips off and back into your bag when the cup goes in the recycling. Fits most 12 oz cups.

PETG, printed flat. Prints flat as a plate, no supports.
MAIN PURPOSE: Start small nails without hitting fingers
Press a panel pin or small nail into the slot that grips it and tap it in while holding the long handle: your fingers stay 100 mm from the hammer, and the three slots take shanks from 1.4 to 3 mm. Pull the holder away sideways once the nail stands on its own.

MAIN PURPOSE: Mark out a carving spoon blank
Lay the template on a split green-wood blank with the notches on the grain line and draw round it: you get a well-proportioned eating spoon, a 46 mm bowl on a 190 mm handle, ready to axe and carve, and every spoon in a set comes out the same size.

PLA, printed flat. Prints flat as a plate, no supports.
MAIN PURPOSE: Carry big sheets of board single-handed
Carry a full sheet of plywood or plasterboard on your own: hook the bottom edge into the J, stand the sheet on edge against your side and lift by the top handle. Your arm hangs straight, the board stays vertical and the sheet no longer needs two people or a wide arm span.

PETG at 100 % infill, printed on its side.
MAIN PURPOSE: Hold leather for hand stitching
A leather stitching clam: glue a strip of scrap leather to the inside of each jaw tip, grip the long spring jaws between your knees and the faced jaws pinch the leather edge, holding it upright and still so both hands are free for saddle stitching with two needles.
