Otoscope Mount for Prusa Mini Nozzle Monitoring

OOPS! My original design was for a slightly improperly built Prusa Mini and my heat block, heat break, and nozzle all sat lower than they should have. I've redesigned the Otoscope mount part to be 2mm higher and uploaded it in a separate STL file.

As soon as I started my very first print with my new Prusa Mini I decided I needed a way to see the nozzle up close if I wanted to do the best 3D prints I can. 

I designed this rotating clip-on mount that attaches to the side of a fan, accepts a 4.3mm wide otoscope (ear camera), and lets me watch my printer churn stuff out on my computer, phone, or raspberry pi.

The angled hole for the Otoscope is 3.35mm wide, with a shallow 5.55mm diameter opening so the camera can slide in a little for better focus.

In the one print I've done those dimensions were exactly 3.3mm and 5.5mm, but I had to shave a tiny bit of material away with a drill bit so I adjusted them slightly. Please let me know if you have a similar otoscope and it fits on the first try. The bolt hole fits an M4x8.

This is the first thing I've designed and put online like this. :)
