Sun Finder for Telescopes

This is a simple sun finder to be used in telescopes. Point at the sun and when the shadow is centered in the white spot the telescope is aligned to the sun (provided the device is mounted correctly).

The front disk is designed to be rinted in two colors, preferably black and white. It needs a color change at 0.6mm height, and then again back to the original color at 1mm height. No supports required. You can print this in any material, but PLA is known to degrade faster under sun light, so maybe PETG or ABS would be better. You will need four 3mm bolts to assemble the parts together.
