MakerWorld name keychain
or NameSTL?
MakerWorld's Parametric Model Maker lets you type a name into a customizable model, like Customizable Name Keychains or Parametric Name Keychain, and download a file for free. If you own a Bambu Lab printer and one of those models looks the way you want, use it. NameSTL is the paid option for curated fonts, joined cursive, bases beyond keychains, bulk export and a commercial licence.

The short answer
MakerWorld is free and very good for Bambu Lab owners who want one keychain. You need a Bambu account, and what you get depends on which model you pick: every customizer is written by a different author, with its own fonts, options and licence.
NameSTL costs money to download ($4.99 per file, or Unlimited at $9.99 a month), and in exchange you get the same 18 tested fonts across every product, script names that print as one piece, seven base types, up to 100 names in one ZIP and the right to sell the prints with Unlimited. We make NameSTL, so weigh that. The wider comparison, including Tinkercad, is on best 3D name generators.
What MakerWorld's name keychain makers are
MakerWorld is Bambu Lab's model-sharing site. Its Parametric Model Maker runs OpenSCAD scripts that authors upload; any variables in the script show up as options, and the model page gets a Customize button. You type a name, adjust the options, and download the result as a 3MF or STL, or open it in Bambu Studio.
There are many name keychain models built this way. Popular ones include "Customizable Name Keychains" (/models/2679660), "Parametric Name Keychain", "Name Keychain Generator [NO AMS]" (/models/2115391) for printers without an AMS, and "Parametric Pixel Art Name Keychain" for a blocky pixel look. Each has its own look, fonts and settings, because each is a separate author's script.
MakerWorld vs NameSTL, side by side
Checked on 2026-09-29. MakerWorld details vary by model; the column describes what's typical.

Using a MakerWorld name keychain
The general flow. Button names and options vary a little by model.
- 1
1. Find a model
Search MakerWorld for "name keychain" and look for models with a Customize button. Check the photos from people who printed it; that's the best preview of the fonts.
- 2
2. Open the customizer
Sign in with your Bambu account and click Customize. The Parametric Model Maker opens with the author's options: text, font, size, colours, sometimes the hole position.
- 3
3. Generate and download
Type the name, generate the preview, then download the 3MF or STL, or send it to Bambu Studio.
- 4
4. Read the licence
Before you sell anything, check the licence on the model page. It's set by the author, not by MakerWorld, and differs between models.
When MakerWorld is enough
You own a Bambu printer
You already have the account, the models open in Bambu Studio, and many are tuned for the AMS. For one keychain there's little reason to pay.
You like a specific style
If a model's look fits, like the pixel art keychain, use it. NameSTL doesn't do pixel fonts or multi-layer designs.
It's for you
A keychain for your own keys or a gift for a friend is personal use, the least restricted case. Still read the model's licence.
You want to tinker
Some authors expose a lot of options. If you like adjusting parameters, a good customizer gives you more knobs than we do.
When NameSTL is worth paying for
Cursive that holds together
All 9 script fonts are joined into one connected piece, so a cursive name doesn't print as loose letters. See the cursive name keychain page.
More than keychains
The same name and font can become a desk plate, a cake topper, a Christmas ornament or a pet tag, not just a keychain. Start with the name keychain generator or any other base.
A class or a market stall
Unlimited turns a list of up to 100 names into one ZIP. On MakerWorld you generate each name one at a time. Details on name keychains in bulk.
Selling the prints
Unlimited gives you commercial use for everything you make with it, so you don't have to check a licence per model. Our guide to selling prints from generators explains the licence types.
Any printer, no Bambu account
The STL opens in PrusaSlicer, Cura, OrcaSlicer or anything else. Owners of Prusa, Creality or Elegoo printers don't need a Bambu account.
Tested meshes
Every font runs through the same export pipeline, and the meshes are watertight, so the slicer doesn't need to repair them.
Type the name you'd put into a MakerWorld customizer and compare. Free to design, pay only when you download.
Where NameSTL falls short
MakerWorld is free and NameSTL's download isn't. If you print one keychain a year, that matters more than any font. NameSTL also has fewer knobs than the most detailed customizers: no pixel fonts, no text along a curve, no layered designs. You get 18 fonts and 7 base types done well, not everything.
Want to make your own model with text instead? Tinkercad is free too; see our Tinkercad keychain tutorial.
How we checked
- Checked on 2026-09-29: MakerWorld listings for the models named above, and Bambu Lab's community forum posts on how the Parametric Model Maker runs OpenSCAD scripts and exports 3MF or STL.
- We didn't test print quality of MakerWorld models; that depends on each model and its author.
- MakerWorld changes often. If a detail here is out of date, the model page is the source to trust.
Questions people ask
Is MakerWorld's name keychain maker free?
Yes. The Parametric Model Maker customizers on MakerWorld are free to use and download. You need a Bambu account, and each model has its own licence that decides what you can do with the prints.
What is the Parametric Model Maker on MakerWorld?
It's MakerWorld's tool for customizable models. Authors upload OpenSCAD scripts, and the script's variables show up as options like text, font and size. You generate your version and download it as a 3MF or STL.
Can I use MakerWorld name keychains without a Bambu Lab printer?
You need a Bambu account to use MakerWorld, but not a Bambu printer. If you download an STL, it opens in any slicer. Many models are built around the AMS and Bambu Studio, so check the model description first.
Can I sell keychains made on MakerWorld?
It depends on the model's licence, which each author sets. Some allow commercial use and some don't, so read it on the model page before you sell. With NameSTL Unlimited, commercial use is included for everything you make.
Which has better fonts, MakerWorld or NameSTL?
MakerWorld's fonts depend on the model you pick, so some have great ones and some only a few. NameSTL has the same 18 fonts in every product, 9 of them script fonts joined into one piece.
Can MakerWorld make keychains for a whole class?
You can, one name at a time: type, generate, download, repeat. NameSTL Unlimited takes a list of up to 100 names and gives you one ZIP, which saves a lot of time for 25 or more names.
