Pinhole Monocle
thingiverse
This is a functioning pinhole monocle designed for use as a reading aid. Hole diameter, spacing and thickness were all chosen with this in mind. The pinholes should allow text to be readable in decent lighting. Included are medium size 37mm monocles and large 40mm monocles. Three versions of each are included with slightly different shapes to conform to the eye. The part should be printed vertically. If the holes are blocked after printing a .040 (1 mm) max diameter tool can be used to clear them. I use a 30 line brim for platform adhesion to insure stability. Updated 5/7/19 - Included the large 40mm sizes
