Name keychain generator
Ring included.
Type a name and the generator builds the whole keychain: a rounded plate behind the letters and a ring for the split ring, exported as one STL. No CAD, and no drilling a hole into the print afterwards.
Keychain mode is already selected. Change the name, font, thickness and colour, then download the STL.

What keychain mode actually builds
Most name generators hand you bare letters and leave the hard part to you. This one models the parts that decide whether the keychain survives a pocket:
A plate behind the letters
A rounded rectangle sized to your name plus roughly 3 mm of padding. Its depth is 40% of the letter thickness, never less than 2 mm, and the letters stay proud of it.
A ring on the left edge
An annulus grown out of the plate's left edge, with at least 3 mm of solid material around the hole. The hole is at least 6 mm across, so a split ring or a small carabiner passes through it.
One connected body
Ring, plate and letters overlap on purpose, so the export slices as a single solid. Nothing to glue, nothing to assemble, no supports.
Any font, including block letters
Separate letters like Anton or Oswald are held together by the plate, so you don't need the thin connecting bridges that flat name prints rely on. All eight fonts work in this mode.
From name to keychain
1. Type the name
The 3D preview updates while you type. Short names print faster and look better on a key ring; anything past 8-9 letters gets long enough to catch on a pocket.
2. Set thickness and font
5 mm of letter thickness is the floor for daily carry. Bold fonts (Anton, Oswald) and connected scripts (Pacifico, Dancing Script) hold up best.
3. Download and print flat
Download the STL and drop it on the plate as-is. It arrives lying flat, which is the orientation you want: layer lines run along the name instead of across it.
Real numbers for one keychain
Measured on a 60 mm wide name at 5 mm thickness, printed in PLA at standard speeds:
20-40 min
Print time
Fast printers land near 20 minutes. A full plate of 8-12 keychains runs in an evening.
8-15 g
Filament
Roughly 20-40 cents of plastic at typical spool prices, plate and ring included.
50-70 mm
Finished width
A five-letter name lands in this range. Scale the STL in your slicer if you want it smaller.
Two-colour keychains without multi-material files
Because the letters sit on top of the plate instead of inside it, the model has two clean height zones. In any slicer you can insert a filament change at the layer where the letters begin: the plate prints in one colour, the name in another.
On an AMS or MMU the swap happens by itself. On a single-nozzle printer the print pauses and you change the spool by hand, which takes about ten seconds and costs nothing.
Which filament to use
PLA
Fine for bag tags, party favours and school projects. It gets brittle with age and softens around 60 °C, which a car dashboard beats in summer.
PETG
The pick for keys you actually carry. Tougher than PLA, handles heat, and flexes a little instead of snapping.
TPU
Effectively unbreakable and silent in a pocket. Print it slowly, around 25 mm/s, ideally on a direct-drive extruder.
Name keychain FAQ
Does the STL include the keyring hole?
Yes. Keychain mode models the ring as part of the body, with at least 3 mm of material around a hole of 6 mm or more. You don't have to add a negative cylinder in the slicer or drill the print afterwards. Keychain slicer settings that stop breakage →
How long does a 3D printed name keychain take to print?
About 20-40 minutes for a 60 mm keychain in PLA at 0.2 mm layers, and 8-15 grams of filament. Eight to twelve of them fit on a 180 x 180 mm bed, so a batch for a class or a market stall is one overnight print.
Do I need supports?
No. The plate prints against the bed and the letters grow upward from it, so there are no overhangs. Add a brim only if you scaled the model down far enough that adhesion gets marginal.
Which font should I pick for a keychain?
Anton and Oswald have the widest strokes and survive the most abuse. Connected scripts like Pacifico and Dancing Script also work well because every letter fuses into the next. Thin decorative scripts look great on screen but chip at the tips.
Can I sell keychains printed from these files?
Yes, commercial use is covered by the subscription. Name keychains are a common first product for a print-on-demand shop: cents of material, under an hour per piece, and they ship as a letter.
