Robust drawer separators / dividers

Drawer seperators for ~17 inch deep IKEA drawers. Designed in Fusion 360 by spousal request and deployed with approval :) I'd thought I'd need to spring load the slots to maintain tension but they are chonky enough to work great without. Can be scaled up or down to fit smaller drawers - I'm pretty close to maxxing out the build plate especially when printing two sets. I sliced this to print as FAST as possible with PETG, cutting every corner possible and they still come out great (0.28 layers, 15 mm^3/s etc.) Prints much faster in PLA but I figure I need these to last years, so the flex is helpful.
