Looks good. Can you apply it to an existing window like a cell phone oleophobic coating? Or do you have to install a new piece of plastic/glass?

AvE did a good video with a spinning viewport.

See, if you need to watch, indicates a lack of confidence in setup and program, reinforced by the encyclopedic safety sticker. That shut me off directly.

We used to do a similar thing on our sandblaster, used the sapphire window from grocery scanner/barcode readers.
They would last forever instead of getting scratched from the sand.
Stuck it on the inside of the polycarbonate window with silicone seal.
The tablet screen protector idea might work for that as well.

$5 Below stores have tempered glass screen protectors for Ipads for, iirc, $3. I used one on the bed for a 3d printer as an experiment once.

Did it work?

Lol. I thought you'd forgotten to include promised list 'Below'.

Yes and No. Yes I was able to print on it. Getting prints to stick required carefully adjusting the bed gap, but it did eventually work. The problem was that the print adhesion to the glass was greater than the glass adhesion to the print bed. Trying to remove a print lifted the whole screen protector. That, combined with the annoyance of it hanging off the sides, got me to go back to masking tape.
