SURVEY: USB Microscope

[ChrisLX200]

Hi guys. I also bought this microscope and wanted a stand. Actually, I found one which is pretty perfect:

But problem is: the ring has inner width of 50mm but the USB microscope has 35mm. Anyone has a clue how to solve that problem?

1) Use a 3D printer to print a suitable reducing collar
2) Use your lathe to machine a suitable reducing collar.
3) Wrap round a lot of insulation tape... :-)

Thanks for your tips!

Anyway, if anyone is interested I asked this seller:

Whether he can do it with a 35mm Ring and he said no problem just write a comment about it. So this is then a good solution in my opinion.

This Koolerton 4.3" LCD 'scope with the aluminum stand has been surprisingly good for an untethered usb microscope. It requires a microSD card. The only issue is the mini-usb charging port is sh!# and one has to jiggle it to charge properly.

These digital microscopes aren't quite my cup of tea, but a buddy of mine on FB forwarded this recently released comparison vid.
