Rack for Universal Lock Holder
This is an accessory for Trekmaster30's Universal Lock Holder.
I really like holding my locks in my hand while practicing. But, if I ever lock myself out of my house I will need to practice on something vertically mounted.
Instead of using screws and such to mount these I find that putting some electrical/duct tape inside creates enough resistance. I do the same thing with mounting my locks inside of Trekmaster30's original design.
You may want to print it horizontally and mess with size a bit to get the right fit.
