Microscope Stand Upgrade

An upgraded stand for this popular and inexpensive USB microscope (Jiusion 1000x and similar).

The clamp that comes in in the kit it's way too flexible, making it really hard to focus. This upgrade uses a simple trick to hold the microscope steadier: the clamp itself gets tightened by the same screw mechanism that locks the position (angle).

Hint: print out of PETG. Note you lose one degree of freedom, but I found that to be a non-issue in practice, because this rotation around Z was redundant with the stand anyway.
