Christmas botton keychains with swappable badge, three print builds
Christmas keychains built around your own pin badge — a bow, a gingerbread cookie, a star, a heart, a snowflake, a garland — with your 32, 44, 50 or 58 mm botton dropped into the middle. Pick the design in the editor, set the size of your botton, and print.
To get a perfect fit, print the Botton Size Test model first: it sweeps a row of borders a step apart, so you can find the tolerance and the hole height your own botton press needs. Every machine presses a slightly different badge, so this is worth doing once before you print one you want to keep.
Christmas designs, any botton size: A bow, a gingerbread cookie, a star, a heart, a snowflake, a garland, chosen in the editor, around a 32, 44, 50 or 58 mm badge.
Ring on top, swappable badge: A ring at the top takes the keyring, and the badge pushes back out through the slot in the base when you want to swap it — one keychain, any badge you press.
Three ways to make it, one knob: Face up stacks the artwork on the base and is the one for a multi-material printer. Face down carves the artwork into the face instead, so the piece prints on its design side. One colour per layer is the single-nozzle build: a stack of slabs, one colour each, with a pause at every boundary to swap the filament.
Round Edges: Softens the outline so the piece reads as a baked cookie rather than a cut slab. The curve spans the base's full height, and the offset beside it decides how much bigger than the drawn outline the piece starts out, so the rounding takes it back to the size it was drawn.
Reference values (Dataprint, China machine):
32 mm circle: −0.1 mm | Hole height: 3.4 mm
44 mm circle: −0.2 mm | Hole height: 4.4 mm
58 mm circle: −0.3 mm | Hole height: 5.2 mm
50 mm square: +0.8 mm | Hole height: 3.4 mm
A negative tolerance means the hole is drawn smaller than the badge, because a printed hole comes out a little wide; the square goes the other way and has to be opened up. Use these as a starting point, not an answer — a different machine will land somewhere else, which is what the size test is for.
