Door peep hole in HAL9000 computer style. HAL logo is included in the PDF file. Use glue to assembly all parts together. Read notes in print settings.
Peep hole in my door was with silver ring so I covered the glass and painted it with black spray. It looks much better in black color.
LED light is not part of the project. I used red LED on the opposite site for photo purposes only.
I recommend to use Hilbert curve as bottom fill pattern only for the top black cover. It creates nice structured surface which is later used as view part.
