RSMA/SMA antenna spacer/tightener
thingiverse
A versatile tool for fine-tuning hex nuts on RSMA/SMA antenna connectors. It enables hand tightening while preventing over-tightening and providing a secure end-stop for the antenna. I'm using it in my MJX Bugs 3 transmitter, where I've upgraded the stock antenna to a pigtail extension with an external antenna. This adapter is essential for ensuring a snug fit. Dimensions: The adapter stands at 4.7 mm tall. A STEP file is available for customization and modification.
