Create new plastic window for Yahica Mat LM lightmeter
I'm currently restoring a Yashica Mat LM. Unfortunately the little plastic transparent of the (still working) light meter is gone. Is there a way to recreate a plastic for this? Without too much equipment (I can't do thermoforming). Options I'm currently looking at is using a thick piece of transparent plastic from a PET bottle. Or 1.5mm acrylic sheet and score it to make 90° angles. It's doming a bit (the original) so that'll be a challenge though.
