Futaba R7003SB receiver

These are my first 3D objects, in 3 flavours:
- antenna holes on the back
- antenna holes on the sides
- antenna holes on the top

This is the tube I use:

I don't know the exact diameter (about 3.7mm) so it was a trial and error design.. But now I can easily plug and unplug the tubes to store my quad inside my carry case.
