Designed to hold a Hantek DSO4102C oscilloscope on an Amazon Basics dual monitor stand. You have limited rotation adjustment and cannot use the quick release function on the stand.
Holes made for M5 x 0.8 x 25mm socket head machine screws, no tapping required.
10 walls on 0.5mm nozzle to give plenty of support to the screws.
I used a piece of aluminum for my lower clamp but added a printable one for the angle grinder impaired. I never printed the lower clamp but no reason it shouldn't work.
I added a strip of double side tape between the upper clamp and the DSO case to make sure there was no slip.
