Designed to print without support at 0.25 mm layers.
Three different sizes: 45, 50 and 55 mm centre-to-centre between adjacent eyepiece cups. The eyepieces are held in place by M3-screws, so six screws (8-12 mm) and matching heat-set nut inserts are needed. In the middle of the central bowl there's a 5 mm hole and a slot for an M5 nut for attachment.
