Printed quick clamp for M3 threaded board

This design includes two types of quick clamps made to adapt to a M3 treaded board.

The Type 1 clamp can rotate around its axe while the Type 2 can rotate and translate 2cm.
For each type different arm length are available to adapt to various uses.
Both clamp are fixes on the board with an M3 screw while the "clamping effect" is provided by a M4 bolt.

Each clamp is composed of 6 printed parts: a base, an arm, a quick-change or fix pivot, an M4 bolt pivot an M4 bolt head and an M4 bolt tip. A short rubber band is used to bring the arm back.
Supports are required only for the "T2 Clamp base" for the rubber band hooks but you may want to use some to print the arms depending on the quality of your overhangs.
