About this model

Simple 20x20 stack mount for the Happymodel EP1 ELRS receiver. I designed it specifically for the rear stack on the TBS Source One v5, but it's standard 20x20 so I'm sure it'll work in a lot of different applications. Designed with TPU in mind, but it would probably work fine in other materials.
