Nut holder for wrench

I designed the Holder for my workshop to keep the working space clean and to keep order.

First you must screw the "Base" onto your background. Now you need some thread inserts and insert them with a soldering iron in the holes (M5 was a good choice in my case.
Then just screw on the "Nut_Holder_Small" on top, and below the "Nut_Holder_Big".
I additionaly painted over the numbers and sanded it away when it was dry, to make them a bit more visuable.
