About this 3D model
This is a simple thumbscrew which can be used to loosen/tighten SMA connectors, as commonly used on FPV equipment. The slot allows it to be slipped over most cables, but there is a closed version too. These connectors are also ubiquitous in WiFi and RF lab equipment. I printed in PETG for a little flex.
