This is a gasket for an NMO antenna base. These antenna are typically used on police and fire department vehicles for two way radio installations. I had an NMO base that has a larger gap between the base and the vehicle body. I recommend using the “1mm with flange" as I feel it has a great weather seal. The flange rolls over as you tighten down the NMO and makes a very positive weather seal!
I had also made a 1mm flat gasket and a 2mm flat gasket before I made the one with the flange. I could not get a thickness that I liked. I provided them here in case someone wants one of these. The gasket with the flange is more versatile and should work in a large variety of applications.
Must use TPU Flex filament. I printed mine using Inland TPU from MicroCenter. There are many other good options.
