This is a remix of a remix of a remix, I think. I don't know where the original was, and I'm not even sure which one I started from, but I suspect it was one of these:

I've included both the STL and the Fusion 360 file. Please keep in mind I'm not a Fusion 360 expert, and I'm sure there are things I could have done better.

My wife's was printed with 10% infill, which cased some problems. That beautiful pink filament shrinks when it cools. The first full layer over the infill (like the bottom of the cartridge slots) would hang over into mid air, which isn't normally a problem, but when this filament started to shrink, it curled upwards, and the print head would hit it. It turned out fine, but it made me get up more than a few times to figure out what was going on. So when I printed mine, I went with 20% infill with a different pattern.
