Eyepiece converter for microscope from 23mm to 30mm

myminifactory

The new microscope I purchased recently came with 30 mm eyepiece lenses. In addition, I bought another set of lenses with a diameter of 23mm. To accommodate these smaller lenses in my microscope, I created a custom converter. Shrinkage is inevitable due to the properties of the filament used - mine were made from ABS plastic. Although the outer diameter fit perfectly into the microscope, the inner diameter required sanding for a secure fit. As it turned out, sanding produced an exact snug fit for the 23mm lenses. To widen the inner diameter and achieve this snug fit, I rolled up coarse sandpaper into a cylindrical shape and used it to slightly enlarge the area.
