Need some help bros, I'm trying to find an arm that will fit my microscope (pic related) but I'm having trouble. Basically I want to upgrade by attaching it to an arm, freeing up space to work on bigger motherboards. From what I've seen I got 3 main options.

>1. Use a microphone arm, attach a ring mount to the arm and put the microscope in. Pros: cheap as hell. Cons: probably hard to get into position, no fine horizontal or vertical movement. Might be a bit wobbly.
>2. Use a monitor arm. Same process as previous option but somehow to attach ring mount to VESA plate or just brute force the plate off the arm and attach ring mount to arm. Pros: also cheap, probably more sturdy than previous option. Cons: also likely hard to get into perfect position.
>3. Use an actual microscope arm

Because I have enough budget I decided getting a real microscope arm would be best, these have great horizontal control and the attached "focusing brackets" have fine vertical control so in theory it sounds like the perfect option. So I was just about to order the following:

Bracket: https://www.aliexpress.com/item/1005002982471324.html

Problems:
>Tube of microscope is much smaller (35mm) than the smallest ring diameter for brackets I can find (50mm) that also fit on a 32mm arm pole. Wouldn't be a problem with adapter rings, however due to stupidly long focus control on microscope tube, can only attach very close to screen hinge so with a large ring like 50mm the screen is forced to be bent backwards.

I can't find any bracket that would fit both on the arm and has at most a 40mm diameter ring (largest diameter that doesn't interfere too much with screen) that also fits on a 32mm pole. I thought about DIYing a spacer tube that would hold the screen above the ring far enough that it doesn't interfere but at this point I'm almost ready to say fuck the fine vertical control and just get a microphone arm.

Any suggestions or ideas?
