Nintendo Switch JoyCon Strap Holder x4

I liked the original JoyCon holder by lasseklein, but I have four controllers, and I'd like them all held together. So I took the design and measurements (via import into Sketchup, probably an easier way but that's what I'm doing for now), bumped it out to the side and made a four way JoyCon holder.
I imagine a six-way holder with built in game storage would be pretty easy as well, so I might try that or a redesign of this with game storage built in.
