I made this mostly for my own use but I'm putting it up here in case anyone wants to remix it. The idea was to repurpose a borescope to serve as a microscope for soldering.

Other than the printed parts, you'll need a borescope (I had a Teslong USB borescope sitting around), 8 M3 nuts, and 4 M3×25 socket cap screws.

Everything should print just fine in PLA with no supports.

I've included the SCAD source (such as it is) in case you need to make adjustments.

The rig pictured uses an old laptop running the Cheese app on Linux, but any camera app should do.

There's also a PCB holder pictured. The files for that are available here.
