Name Keychain STL: Make, Print and Price It

Make the STL

1. Open the free STL generator and choose the Name keychain template.
2. Type the name and choose a font.
3. Adjust the size, the base and text heights and the ring position.
4. Rotate the 3D preview and check the estimated weight.
5. Download the STL — or a multi-colour 3MF for two colours.

The model is generated on your device; nothing is uploaded. Downloading the name keychain as STL works on the free plan (one a day). Pro adds more fonts, more templates and the multi-colour 3MF.

Design tips

• Keep strokes at least about twice your nozzle width (0.8 mm with a 0.4 mm nozzle); thin script fonts lose detail.
• A base of about 3 mm and raised text of 1–1.5 mm feel solid and print fast.
• Leave enough material around the ring hole so it does not snap.
• Short names read better at keychain size; for long names, increase the length rather than shrinking the letters.

Printing in two colours

With a multi-material system (e.g. AMS): open the 3MF in Bambu Studio or OrcaSlicer. The base and the text arrive as separate parts already assigned to filament 1 and filament 2.

With a single extruder: because the raised text starts on top of the base, one filament change is enough. In the slicer's layer preview, add a colour change (or pause) on the first layer of the text, then swap the filament when the printer stops.

Print settings

• PLA, 0.2 mm layers, 2–3 walls, 15–20% infill.
• No supports needed — print flat, text facing up.
• A clean build plate matters: the whole part is basically a first layer.

What does a keychain cost?

A name keychain usually weighs only a few grams: 5 g of PLA at $0.025 per gram is $0.13 of filament. The price is driven by everything else — the ring, packaging, your time for each personalised order and marketplace fees.

That is why batching pays off: 30 names on one plate cost about $3.75 in filament and a single print setup. On the Pro Business plan the generator creates a whole list of names in one go.
