Pinhole Monocle

thingiverse

This is a precision-engineered pinhole monocle designed specifically for reading purposes. Carefully calibrated hole diameters, spacings, and thicknesses ensure optimal text legibility in a wide range of lighting conditions. Three medium-sized 37mm monocles and three large 40mm monocles are included to accommodate different eye shapes. To facilitate secure printing, the part should be oriented vertically during the printing process. If holes become obstructed after printing, a precision tool with a maximum diameter of .040 (1 mm) can be used to clear them safely. To ensure stable platform adhesion, I recommend using a 30-line brim setting.
