About this 3D model

Rain Poncho for "GoPro Hero3 mounting frame" I developed this model for these requirements: Mounting system must be light as possible. (for helmet mount use) Splashproof function is needed only in rainy condition, and must be added easily. USB port must be accessible. (for all day use) USB covers for genuine combo cable(dia 5.8mm), common cable(dia 3.8mm), and thin cable(dia 2.5mm). You need to embed a transparent plastic plate (4cm*3cm) in the window. Clearance between "GoPro Hero3 mounting frame" and this model is 0.2mm. Clearance between this model's body and USB cover is 0.1mm. (very tight) [Japanese]
