I made these to fit in the Dewalt Tough System organizer cups. The stock cups nest in each other and have little ledges to keep them from inserting too far. This is perfect for allowing smaller cups to fit inside and take advantage of any extra space you may have going to waste.
I've got cups that fit both the large and smaller cups. The smaller cups can be a single cup or one with a divider and the larger cups have 0, 1 or 2 dividers.
Looked at my other tough system organizer without a clear lid and they have 2 more cup sizes in it. I'll work on making some nesting cups for those too if there appears to be interest. I don't think that box is quite as popular though.
Added a large box with a divider going long ways
They're plenty strong at the settings listed, lower infill should also work.
Print in at least PETG so they can be left in a vehicle in the heat without warping.
You may need to trim the bottom edge after they print if your first layer is too squashed. The tolerance is pretty tight so the little extra material on the first few layers can make for a tight fit.
