My son's rowing team needed handle/strain relief on the mic box on their boats. Designed these and decided to upload them cuz I'm quite proud of how they turned out! Uses #2-56 screws and one cable tie. Custom-fit to the rubber plug they use.

V2 - once I printed out the initial version and tested the 'install', I didn't like the cable tie around the body. I redesigned with screws at the mouth and added more substance for the screws to bite into. Printed in PLA, although I might switch to ABS, although one would need to use a brim an do some trimming after done. We will see how they hold up to the rest of the season! Note this didn't need supports.
