Using this adapter screw is easy. First, if you're connecting a tripod to a camera, just screw the 1/4' end of the adapter into the tripod with a 1/4' machine screw. Then, attach the 3/8' end to the camera with a 3/8' thread nut. When 3D printing an enclosure, drill a 3/8' hole in the enclosure and carefully glue the adapter screw into it. As for maintenance, keep it clean and dry. Avoid using it with excessive force as it may damage the threads. If it gets dirty, you can use a soft cloth to wipe it gently. Also, store it in a cool and dry place when not in use.
