In general it does (sort of) work, but the dimensions are totally off. The width of the battery grip is almost 3mm wider than its supposed to, the cutout for the battery's clip is also quite a bit too large, so it slides down more than it should while at the same time wiggling from left to right and if you want to take the battery out you always pull of the entire holder, because the hook mounts are also way too big.
I ended up tossing the print in the trash and remixing the most popular mount for the universal hooks.
