Anyone else with a Pico GX noticing this?

Really odd, I did not think 3D printed plastics yellowed.

My Alcon 2020 cart also yellowed significantly, that slighly translucent resin seems to be susceptible to it.

Anyone know of a way to prevent it? I did not realize that modern printed resins did that. If I had access to a replacement sticker I’d consider dismantling the card and spraying it once over with a cream undercoat and Matt yacht varnish. The same way as I did my insanely yellowed Saturn save memory card to match my import Japanese Saturn.

Actually I don’t fancy PicoGX’s original case color from the very start. So, Is there any 3D models available to download?

I would like to print a case with contrasting colors.
