About this 3D model

The Orange Pi 3B case comes in two versions: a hot press nut version and a self-tapping nut version. The self-tapping nut version uses M2.5 screws, and due to printing tolerances, the designer's bottom holes are also 2.5mm. Please note this. The top cover comes in two versions: a 4010 fan version and a fanless version. The locking screws are M2.5*20mm. Additionally, an Orange Pi antenna holder was designed, which can secure the antenna in place.
