Morse Straight Key

thingiverse

I suddenly be interested in the radio, and now attracting me is the simple pureness Morse Code. Refer to other people designed CW key, I can't find one that satisfied me, So I decided to make my own one. All screw and bolts are M3, the spring can get from a battery box. And I haven't take a full consideration about this design, such as the hole for bolts is overhang without support.
