STEMFIE Kits
A kit is a complete build project: every part you need to print, in one download. Pick one, print it, and build it. All kits use standard STEMFIE parts, so everything you print can be taken apart and reused in the next build.

Every kit has a number
Each kit carries a STEMFIE Project Set number, written SPS-000001 and counting
upward in the order kits were published. It is assigned once and never reused, so it identifies the kit
everywhere: on this page, in the file names, and on MakerWorld, Printables, and the other repositories,
in the same way that an SPN identifies a single part. Search for it above, or quote it when you ask for help.
Why kits live in several places
Some kits can be downloaded here as a ZIP file. Others are published only on MakerWorld, Printables, Thangs, or Thingiverse. Kits marked "Support STEMFIE on …" help the project when you get them there: on Thangs they are premium kits whose price is a direct contribution; on MakerWorld they are the kits that use Maker's Supply hardware, and printing or boosting them earns points for the project. Following STEMFIE on any of these sites is a free way to support it.
The STEMFIE Standard and every individual STEMFIE part are free to download, and always will be. No account, no catch. Some curriculum material and premium kits may carry a price; every purchase funds the development of the free system.
⚠️ Contains small parts that are a choking hazard. Not suitable for children under 3. Suitable for ages 3 and up under adult supervision.
