I made this for my brother's TOMLOV DM09 which has a short stand. I understand the microscope and mount are rather generic (Hayve, Leipan, etc.). So maybe it will work for your microscope too.

The threads are pretty small so you'll want to print at 0.1 layer height. Use a random z-seam to make it easier to “break-in” the threads. I found a large brim and some glue stick necessary to print vertically.

Includes files for 100mm(pictured) and 150mm extension. You may also want to print the test threads first to check tolerences.
