Simplified Banggood Multi Protocol Tx module case base for Taranis

This is a simplified version of the (Taranis) case bottom (made by Nebbian) for the 4-in1 module. After printing the original one (in ABS) and the release tabs broke off the first time I squeezed them and the screw holes just crumbled. So I redesigned it from scratch to use less plastic, stand up to more abuse, and take less time to print. It works great! Note: this remix uses Nebbians original cover.
