printing out a case for my Antminer S9. Currently on 2/4 of the body, already printed out legs. it'll take a while but it's going.
I've been running the S9 for about 1 month and nearly made back .5 mBTC so far and warmed my apartment with it, so considering it a win the whole way.
if you've got an S9, you can get the files/assembled case here : https://www.cryptocloaks.com/the-future-of-space-heaters-s9-bitcoin-asic/
