Quick mm Socket Wrenches

I've lost my 8mm wrench, and my printer had a loose wheel nut. I've rapidly designed a socket wrench I can print in 10mins or less. This is what I cud come out with fast, and worked great from the first iteration.
// EDIT //

The resulting 8mm Wrench was strong and durable, so I've decided to start making a small set. At least for the small sices one just happend to need from time to time. Also, adding a marking with sice to identify them.
