6mm x 5mm mini microphone cosplay cover

These were created as decorative covers for 6mm × 5mm (diameter/height) mini microphones used in Cosplay armor. (So I can hear what going on around me since the helmet makes hearing difficult.)
They have a 9mm diameter inner hole on the bottum so they mic can be cushioned with 1/16" neoprene wrapped around it. 2 holes on the bottom are set to work with 4-40 screws to be held onto the armor.
