I bought indoor electronic TV antenna. It was china made product with case from poor material. When the case was broken but antenna still working I decided to try replace it with 3D printed one. It was little bit complicated because all electronic parts were fitted on this case. I created 3D design in TinkerCAD.

Print instructions

It was printed from Prusa PLA, layer 0.2mm, fill 20%, without support. Thre are two parts of cover: top and back side.
