20mm conduit end connector. Useful for joining conduit to timber or other materials. 20mm conduit is a snug fit within the connector, and can pass straight through into a penetration.
Low price and wide availablity make conduit useful beyond it's intended use - it's a great building material for many projects. This is the first in a wide range of 20mm conduit connectors that I intend on publishing on Thingiverse.
Please comment what you think about this connector and let me know if there's any other connectors you'd find useful.
