Minimal Modular Card Sorting Trays

I wanted some trays for sorting cards in nice piles without a big bulky tray to buy store or requiring tons of filament or storage space. About 10g per tray, in mirrored sets which can nest (as pictured) for more compact storage. 2 versions, compact and near full sizeCompact: Better for more smaller storage but a little fussy for full size cardsLarger: Nearly full card widthCould be expanded to wider than card-width and keyed for interlocking to support. Currently just focused on having tidy piles. Also, turns out 6 of the larger size nest and fit nicely in the pencil-case tins
