Portable solar panels - mounting system

Motivation: create off-grid solar portable low-power station, at 5V, to charge powerbank.

Simple and portable modular solar packet, for panels 60x110 and 110x136.
One segment of this chain was build from two smaller (60x110) panels at the edges and one big (110x136) at the center.

Big socket is built from two "half"s - "socket_136x110_half.stl".
Small socket has two versions with and without hinge on the longer edge.

Chain can be extended as you wish by using short and long connectors alternately.

Whole system can be mount on pvc 1/2'' frame with "handle_pvc_0.5''.stl" model.

PLA is strong enough, but due to thermal energy from sunshine, so there can be weaker.
