Printable cheshire style collimator.
Print using PETG/PLA or other material with neglible warping. Dimensional accuracy and shape are critical. Print using 0.25mm (maybe 0.4 mm will be also ok) for best accuracy. This take time but we need real precision here.
- Use black for body
- Use any color for depth adjuster and knob
- For rectile, I recommend using two colors. Use white for base and change to black for rectile pattern.
Use tiny holes in body to mount some straight and stiff wires. Acupuncture needles are ok, Personally I have used fused silica tubing leftovers but this is quite exotic. Use a little glue and make sure noithing sticks out of the body. Then, glue rectile so it is very well adjusted with wire cross. Knob and depth adjuster accept M3 screw and nut. It is used to make sure that you are observing from the focal plane.
