I did some searching and couldn't find anything on APUG, LFF or even Google. I know it's been talked about so maybe I have to work on my research skills.

I'd like to make some 8x10 floating lids and can't seem to figure it out. I can't find lids for sale (without the tanks anyway). I only NEED one for my developer because I'm getting sick of spending $5 on replenishing every time I run film through every 2-4 weeks. But for a DIY project, I'm sure I can make 3 for next to nothing. Some thoughts? Experience?

As always, thanks in advance!
