C-Mount Adjustable Microscope Stand

I threw together this USB Microscope Stand for my 14MP C-Mount Microscope with 180X Lens I purchased off of eBay. I also own one of the cheaper $20 2MP USB microscopes I purchased off of eBay and I have included an adapter for it as well. I wanted to make the stand modular so the adapters are easily exchangeable and also new adapter for different applications can be made and used as well. All parts can be printed on a 200x200x200mm bed 3D Printer. If you own a printer that can go up to 300mm in height like my CR-10 then you can printer the 300mm tall rod instead and take advantage of an extra 100mm of adjust height. I also included a DIY LED ring light mount that can be used for different camera lenses as well.

As for the printing I used PLA with a layer height of 0.15mm, 3-Layer perimeter top and bottom layers and infills ranging from 5-15%

Hardware:
Qty (4) - #8-32 x 1/2" Machine Screws (If you only have Metric then you can drill out the 4 holes in the base to fit what you have.)

As for the 3D printed threads, they fit a little tight at first, but if you slowly work them in and out they wear in a little start to move smoothly, Printing threaded parts at 0.1mm layer height will be helpful (include parts with internal threads)

I used this for the LED ring light and I soldered a connect and used a 12VDC wall power supply:
