This is the official model from Tidbyt for the wall-mount-kit that they retailed for $14.99. It appears that it was made out of aluminum but they are sold out now. Luckily they were nice enough to include the STL so I'm including it here to make it easier to find. I would make it pretty beefy since their version was originally aluminum so I'm going with 4 walls and 20% infill. I didn't get my tidbyt yet but I'll post a make when I have it in hand.
