6mm Knob using Rivet-Nut Insert

Description
6mm Knob using Rivet-Nut Insert, Nut-Sert, or Nut-Cert I wanted some knobs that matched the blue CF arm.   https://www.bulletpointmountingsolutions.com/   Here is my fix. I used 3D Fuel PRO-PCTG (Cobalt Blue) https://www.3dfuel.com/products/pro-pctg-cobalt-blue-1-75mm McMaster-CARR Rivet Nut (QNTY-1) https://www.mcmaster.com/95105A183/ McMaster_CARR 6mm SS Bolt 30mm Long (QNTY-1) https://www.mcmaster.com/91287A903/ Added in Optional_RIV-NUT-CAP_v3. This just fills the hole at the end of the RIV-NUT and is purely cosmetic. It is a snap it fit.   Just added a bolt retainer clip. (pictured below). For those times when you are trying to remove or add a device by tightening the ball with the clamshell halves. Takes care of the pesky bolt jumping out to the ground. Completed and installed parts. NOTE - Rivet-Nut is used as an insert for this product using a soldering iron at 330 deg C to melt it in. It is not compressed.
