3D Print Snap/Interlock System (user modelmaker_PVG's design!)

See caveat below! A remix to give different sizes for glue-less interlocking mechanism for 3D prints. 5mm, 10mm, 15mm, and 20mm included as stl. Both with and without a base. Just for ease of design.

Caveat:
Polypanels have great connectors and a whole community around it if that could work better for your idea. Also, the idea behind them are really cool. This is more aimed toward connecting flat things semi-permanently with seamless connections, such a leg connecting to a body of a miniature, or a large print where it has to be split up and the upper print connects to a lower print. Generally best used on flat surfaces as well, though not necessarily.
