This is my first remix! I hacked up a 3x3 multiboard to get this lovely hook with correct hole spacing!
Initially I wanted to make this from a snap, but kinda wanted to keep it simple to print. As it turns out, the small threads make for a really nice, sturdy mount which I'm not sure I would've achieved with the snaps.
You can use the 13 mm Small Thread, Flat Head, Shank T-Bolt to attach this to a Multiboard and hang it off whatever (in my case a desk upright). It makes for a flush fit to the bracket, which I promise you I did not plan.
Print orientation should be on its side, I used 3 walls because that's what the rest of the Multiboard stuff uses, otherwise normal settings for PLA.
All credit for the original Multiboard design goes to Keep Making!
