Summary

This is made to fit to the standard 18mm diameter Drain Rod thread, with a 4mm pitch. You can then insert a 6mm camera (boroscope).

Thanks for the inspiration SR1992 (https://www.thingiverse.com/SR1992), your design gave me some good ideas: https://www.thingiverse.com/thing:4977296

Post-Printing

It may be necessary to run through the hole with a 6mm drill, to make sure the camera will fit okay. The supports are not too difficult to remove, you will need to cut/break the cylindrical support and as you peel it off the other supports should come with it.
