An "I heart MY CAT" keychain in black, white and red, for every cat person you know.
The souvenir "I heart" mark with MY CAT underneath: a black plate, white letters raised on it and a red heart raised higher still. Small and bold, it reads from across a room, which is exactly how cat people like to announce it. Good for adoption anniversaries, birthdays, International Cat Day and new kittens.
Made with our free I love you keychain generator, not modelled by hand: we typed MY CAT, set the width to 55 mm and the white and red rises to 0.8 mm each, and left everything else at the page's defaults (the Fun & Bold font, the keyring hole beside the I). The zip holds exactly what the tool downloads: a 3MF with the plate, the letters and the heart as separate coloured parts, and a one-piece STL. It comes out 55 by 39 mm and 4 mm thick, and prints flat with no supports.
Print one per cat in the house and tie them together on one ring. Cat people will not be offended by the excess. Printed in one colour it still reads, because the letters stand proud of the tag; for black, white and red, a single-nozzle printer needs two filament changes, and the print sheet in the zip says where.
Shown as a 3D render of the printed keychain with a steel split ring, not a photo.
Print it flat as exported: no supports, 0.4 mm nozzle, 0.2 mm layers.
Multi-colour printer: open the 3MF, each part already carries its colour. Single nozzle: add a filament change in the slicer's layer preview for white at 2.3 mm and red at 3.1 mm above the bed.
Let the bed cool before you lift the tag off, so the thin edges stay flat.
Open the split ring with a thumbnail or a small screwdriver and wind it through the hole.

Yes. Type the name into the free I love you keychain tool, for example LUNA or OLIVER, in place of MY CAT. The word is set to fill the width of the I and the heart, and the page tells you when a long name makes the tag grow.
The black, white and red of the file are the classic souvenir look and read best. For a softer take, print the plate in a pastel lilac or grey and keep the heart red; the colour swaps happen at the same heights either way.
Start in black, then change to white at 2.3 mm and red at 3.1 mm above the bed. Those heights are measured in the file, from its lowest point, which is where your slicer puts the bed; add each change in the layer preview where the new colour first shows. With a multi-colour printer, skip all that and open the 3MF.
