CP33 Telescoping Tailhook adapter

thingiverse

This adapter demands 2 - 5/16" aluminum rods for optimal performance. The tubes of the body portion may need some drilling out to accommodate these rods perfectly. A binder clip serves as the spring mechanism, secured by inserting an Allen wrench shaft through it. To attach it to the printed body, two small wood screws are employed. As depicted in the jpg above, the Allen wrench shaft locks snugly into small grooves cut into the aluminum rods. I strongly advise using a Dremel with a cutting wheel for this precise task.
