5x2 Gridfinity tray to hold 3/8" and 1/4" 90 tooth ratchets from E Ding tools (sold as Icon, EPAuto and many more brand names). The ratchets sit low enough that other trays can be stacked on top.
I put both wrenches into a 5x2 tray rather than separate 5x1 trays as single-width trays were a little to narrow for me to comfortably get my fingers around the wrenches in.
STEP file included for your modification pleasure.
Edit: I've added the STL for the 5x1 tray for a single 3/8" ratchet in case your fingers are daintier than mine.
The author marked this model as their own original creation.
