Small Outdoor Faucet key handle

I keep losing my outdoor faucet handles, and it's frustrating because they're easy enough to buy, but I never seem to find one when I need it. A simple solution is to print a bunch at once and leave them in the faucets. There are already several faucet handle designs available for printing, but I wanted one that was small, looked good, and could be printed in PLA. Most of the existing designs look like copies of commercially available keys. These require printing in ABS because they're too thin to withstand any force if printed with PLA. The common type of key for outdoor faucets where I live (Sweden) is called an 8mm key, but the square taps in my faucets are actually a bit smaller (7.5mm). I'm not sure why that is, so I designed a handle that fits my faucets. You want the handle to be dense and snug since it needs to stay in place and handle a bit of force. I printed mine on 0.2 mm layer height and 75% infill. As usual, you might need to adjust the scaling slightly to get a snug fit, but the design prints with perfect dimensions on my printer, which I've tried to calibrate as precisely as possible.
