This is a fully printable boom arm with a printable adapter for either a 3/8in or 1/4in mounted microphone.

Objects should be printed as the models are oriented for smallest use of supports (I used build plate only supports.

a basic setup need 3 screws+1 for each arm (with 2 arms that's 5)

if using a weaker filament the microphone mount may need to be printed laying down, but that increases the risk of supports ruining the thread, so do so at your own peril.

Print uses 98g with my settings and complete setup with 2 arms. (3 walls, 3 top layers, 3 bottom layers, supports on build plate only)
