Giá đỡ tuýp T-handle lục giác Harbor Freight

I got this set of convertible T-handles / Hex drivers from Harbor Freight and they didn't come with a holder like some of the other T handle sets did, so I modeled this one up so they could be stored in the same manner.

I adjusted the model slightly from the photo since I had to do some post processing on the slots and holes, and wasn't happy with how flimsy it was so it should be more robust now.
