Diffuser is quite useful for preventing overexposure on the webcam (if installed). Making it a lot easier to see the print clearly.

Slightly difficult to install due to the snug fit, but once it's clipped into place, no glue or screws are required.

1 layer wall, 0 infill gave me the best result for brightness and diffusion. Print in white for best transparency and diffusion. Colored filaments work, but will drastically cut down the brightness. Haven't tried clear filament.
Model is made slightly short on both ends on pupose, so that it clear the rods, giving it full range of motion.

Orca Slicer Project file for V400 included

Great print to for any leftover filaments, as it doesn't require much to print.
