I'm not going into the controversal discussion about the glasses, there is a lot information out there, inform yourself and use the glasses at your own risk!
The glasses are printable without support and inplace. Using a standard layer height of 0.2mm and 0.4mm nozzle the total print time for one model will be about 58 min with a PRUSA-MK4, the same duration applies for a MK3S with 0.4mm layer and a 0.6mm nozzle.
I publish three models with different pinhole diameters, starting from 1.0mm, 1.2mm and 1.4mm. The diameter is marked (embossed) in one ot the side bars. Using a smaller diameter enforces a larger depth of field.
To have the best effect the color of the filament (PLA or PET) should be black.
Sidenotes: as the pinholes are printed vertically, bended glasses are possible and first layer problems are avoided with this technique.
