C-Mount Adjustable Microscope Stand

thingiverse

I assembled this USB Microscope Stand for my 14MP C-Mount Microscope with a 180X Lens that I bought from eBay. I also own one of the less expensive $20 2MP USB microscopes I purchased from eBay and have included an adapter for it as well. I wanted to make the stand modular so the adapters are easily interchangeable, and new adapters can be created and used for different applications as well. All parts can be printed on a 200x200x200mm bed 3D Printer. If you own a printer that can reach up to 300mm in height like my CR-10, you can print the 300mm tall rod instead and take advantage of an extra 100mm of adjustability. I also included a DIY LED ring light mount that can be used for different camera lenses as well. As for printing, I used PLA with a layer height of 0.15mm, 3-Layer perimeter top and bottom layers, and infills ranging from 5-15%.

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 connector and used a 12VDC wall power supply: https://www.aliexpress.com/item/B86-Hot-2Pcs-Bright-White-100mm-Angel-Eyes-33-SMD-LED-Ring-Car-Light/32777360207.html For anyone who does print this, your feedback would be much appreciated.
