How Digital STL Downloads Work (And What You Actually Get)

Never bought an STL file before? Here's exactly what you get, how to open it, and how to get it from file to finished print.

What Is an STL File?

An STL file is a 3D model file. It describes the shape of a 3D object as a mesh of triangles. It's the standard format for 3D printing — the same way a JPG is the standard format for photos.

When you buy an STL file from us, you're buying the digital blueprint. You then take that blueprint to your 3D printer and manufacture the physical object yourself.

You are not buying a physical product. You're buying the instructions to make one.


The Process: Start to Finish

Step 1: Buy the file

Click Buy on any product. Check out with your card via Stripe. Takes 30 seconds.

Step 2: Get your download link

Within seconds of payment, you'll receive an email with your download link. Click it to download a ZIP file containing your STL files.

Step 3: Open in your slicer

A "slicer" converts the STL model into instructions your printer understands (G-code). The most popular slicers are:

  • **Bambu Studio** (for Bambu Lab printers)
  • **PrusaSlicer** (for Prusa, most other printers)
  • **Cura** (universal, free)
  • All are free to download.

    Step 4: Set your print settings

    In your slicer, choose your printer, material, and settings. Most of our files include recommended settings in the description. The most important ones: layer height 0.2mm, infill 15–20%, supports off (unless noted).

    Step 5: Send to printer

    Export G-code to an SD card or send wirelessly to your printer. Press print. Done.


    What Comes In The Download

    Typically:

  • One or more STL files (some designs have multiple parts)
  • Sometimes: multiple size variants
  • Sometimes: print-in-place and assembly variants
  • No instructions PDF is included by default — everything you need is in the listing description. If you have questions, message us.


    What If I Don't Have a Printer?

    You don't need your own printer to use STL files. You can send the file to:

  • **[Craftcloud](https://craftcloud3d.com)** — online print service, ships to your door
  • **[Treatstock](https://www.treatstock.com)** — find local print shops
  • **[Shapeways](https://www.shapeways.com)** — premium materials including metal
  • Local makerspaces or libraries often have printers you can use for free or a small fee

  • Your Download Link

    Your download link never expires. You can re-download any file you've purchased at any time by clicking the link in your original email.

    If you lose the email, contact us at bodhinsshop@gmail.com with your order details and we'll resend it.
