The souvenir "I heart" mark with MOM underneath, as a flat three-colour keychain: a black plate, white letters and a red heart raised above them. Short and bold, so it stays readable even after years on a busy keyring. Good for Mother's Day, her birthday, or a thank-you from a child who helped print it.
Made with our free I love you keychain generator, not modelled by hand: we typed MOM, set the width to 50 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 50 by 39 mm and 4 mm thick, and prints flat with no supports.
Print a few in one go: one for Mom, one for Grandma's keys and one for the car. 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, and it is a nice job for them: they can pick the filament colours, press the button for each colour swap when the printer pauses, and thread the finished tag onto a ring. Nothing about it needs tools or sanding.
Yes. Open the free I love you keychain tool, type MUM, MAMA or any other word in the text field, and it sizes the word to the width of the I and the heart for you, then gives you a new STL and 3MF.
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.
