The microscope eyepiece adapter was easy enough: a cone with a cylinder punched out of it:
The thin part of the tip is four threads wide around the eyepiece OD, which makes for good fill.
The bottom has the usual four alignment pin holes:
The main tube opening ID is equal to the diameter of the flat rim around the microscope eyepiece, which provides a positive stop with plenty of surface area.
It looks about like you’d expect on the microscope, with the LED ring light from Planet Barbie around the objective lenses:
The lowest magnification is much higher than I expected; it’s about 2.5 mm across. This is a 1206 SMD resistor:
The highest magnification shows details of a laser etched numeral:
The alignment obviously isn’t up to par and I think the exposure needs some work. All in all, though, it’s usable as-is.
