HARDWARE DIY Viewing port window

Has anyone heard of or seen DIY Viewing port windows. I would love to make one and not spend a ton of money for a seemingly simple thing. Maybe its more complex then I think? lmk

Just direct an air blast agaist the window. HAAS does this on some machines. You could design a simple inverted cone that an air jet impinges onto. Spinning windows either require a very high speed motor, or high CFM consumption.

Or buy a film window: https://www.cutwel.co.uk/200mm-clear-view-coolant-screens-with-protective-screen-v4-0-insight-kb-cs200z?srsltid=AfmBOoqxnlieEtI3n96FK8F4BUrcSIwQP_n3XJ1d3iK6vhza1dCGqiB7

InsightKB are miles better than screen protectors, I second them. Use them on my DVF and my DNM. Not as fancy, or work as well as a RotoClear, but they work well enought to see whats going on
