As you can see I have try to do also a mirror to project to 90° on a wall instead of the roof.
The screw on the side are there to adjust the height to have a perfect image.
The text is printed on a small part, print quickly and exchangeable easily
The result is not so bad, but the light is not bright enough.
I have try with a more powerful bulb (https://www.amazon.fr/gp/product/B07BT6RCSN/ref=ppx_yo_dt_b_asin_title_o06_s00?ie=UTF8&psc=1), it was much better, but the heat generated has melt the PLA :(
If somebody wants to improve and maybe try to print it with a more tough heat material, it would be fine to test if it works.
Maybe also add a heat exchanger or a fan..
