Sources for 3D Printer Files

While drawing your own parts using CAD software and printing them out is amazing, there are lots of things you can download and then print without having to draw anything.  These sites have a combination of free and purchasable files that you can choose from.

Our Ultimakers work with .stl, .3MF, and .obj files so look for those first but it’s possible to convert other solid model file types (like files from Fusion 360 or Solidworks) into a printable file fairly easily.

  • Cults 3D – popular site with lots of files
  • Thangs – new site with easy to use format
  • Thingverse – Used to be my go-to but now is more corporate
  • GrabCAD – most models won’t be in .stl format but there are many more engineering-type models here than on Thingverse
  • MyMiniFactory – Haven’t used this much either but it appears to have some nice models
  • YouMagine
  • Pinshape
  • 3D Warehouse
  • 123D from Autodesk – Haven’t used this one but it appears to have a lot of models and might be worth some exploration.
  • Turbosquid – never used it but appears to have lots of models, lots aren’t free though

STL Search Engines:

  • stlfinder – search engine for .stl files, uses above sites plus others
  • yeggi – another .stl search engine

Feel free to send me links to other sites you’ve used to find .stl files.
