Make a 3D-printed keychain with a name or logo
A tag, a name, a hole for the ring. Here is how to make one that prints cleanly on the first try and survives a pocket, with sizes that work on a standard 0.4 mm nozzle.
Settings that print well
Step by step
- Open the editor and choose Box from the shape library (key B). Click to place it, then set Size to about 60 × 25 mm, Corner radius 5 mm and Height 3 mm.
- Pick the Text tool (T), click on the tag and type the name. Bold fonts such as Oswald Bold or Roboto Black print best at small sizes. Set Height to 1.5 mm and Lift above bed to 3 mm so the letters sit on top of the tag.
- Add a Cylinder hole from the shape library near one end and set its diameter to 5 mm. Holes cut through whatever they overlap.
- Select the tag and text together (Shift+click) and use Align → Middle to center the name, then nudge it with the arrow keys.
- Open Print preview (key L) at your layer height. Red marks mean a stroke is thinner than your nozzle; make the text bigger or choose a bolder font.
- Export STL for a single color, or 3MF to keep the tag and the name as separate colored parts.
Questions
What size hole do I need for a key ring?
A 4–5 mm hole fits most split rings. For a thin jump ring or ball chain, 3 mm is enough. Leave at least 2.5 mm of material between the hole and the edge so it does not snap.
Which fonts work best?
Bold, simple fonts. Script and thin serif fonts often have strokes thinner than a 0.4 mm nozzle can print; the print preview marks those spots in red.
Can I use my own logo?
Yes. Use Import image, choose Outline, and the logo is traced into smooth shapes you can place on the tag. Only use logos you have the right to use.
Can I sell the keychains?
Selling prints or files is commercial use, which is included in the Seller plan. Free, 7-Day Pass and Maker plans cover personal use and gifts.
