Customizable stereographic picture projector v3

This thing adds a simple lamp chassis for my stereographic picture projector v2: . The projector itself now has a thread to mount it to the chassis which can be easily replaced to experiment with different lamp designs without having to reprint the whole thing. The chassis that is generated allows to mount a LED with a cooler exactly at the north pole and create a simple lamp. I used an 1W and a 10W Highpower-LED.”
