A lens adapter designed for the Microsoft Lifecam studio and a generic wide-angle lens and connect to the parts listed here: https://www.printables.com/model/258750-camera-side-mount-prusa-i3-mk3s
The lens I used is here https://www.amazon.com/dp/B00B49LOMO?psc=1&ref=ppx_yo2ov_dt_b_product_details
If I recall the lens which fits into the plastic is roughly 35mm outside diameter (the threads are for a 30mm camera but the outer diameter of the barrel is about 35mm).
The author marked this model as their own original creation.
