Files are either supplied as STL files or STEP files. STL files cannot be edited, but STEP files can be modified in programs like Fusion 360 or Plasticity. The reason I supply a step file on occasion is so you may adjust or play with tolerances, or make your own modifications, where it would be relevant.

Before purchasing 3d files, please watch the project videos, linked in the product descriptions, to make sure you understand everything you need to know.

You can still get the 3D files from me, and then find some one on Facebook Groups locally, who will print them for you, for a fee. Alternatively, there are online services that will do this for you too.
