1 3/4" to 2" Roll Bar NMO Antenna Mount

Made this model to attach an NMO antenna to a roll bar of a Honda Pioneer 1000 which is 1 ¾". I decided to make it fit up to a 2" bar and used a bushing to bring it back down to 1 ¾" for my use.  I designed it to use 3/8" hole NMO mounts. It uses 2 ½" wood screws or similar for fasteners. I printed the main body parts, Antenna_Clamp_C and _D, from simple PLA. I used 4 walls w/ 15% infill. I was in a rush to print it so I used .3mm layers. Printed at the hotter end of the PLA's specified temp range to help layer adhesion.

The bushing that brings the model from 2" to 1 ¾" I printed from TPU.
