Eclipse-tested pinhole projector adapters for an 8 cm diameter tube (poster-type tube). The part where the light is projected is prepared for extending the tube to accurately focus the projection. The pinhole part has 3 sets of holes, each set having a different diameter so the projected light is always bright enough. No supports are necessary
The pictures show the setup of the projector and the real-life test. I had to make the pinholes bigger due to printing tolerance.
