I didn't like the included holder, so I made this centerpiece for the DDD system. This is the set: https://www.parktool.com/en-us/product/sliding-t-handle-torx-compatible-wrench-set-tht-1
I also made little label tops for the set here: https://www.printables.com/model/468021-park-tool-tht-1-sliding-t-handle-torx-top-labels
I also made a holder for the hex set here: https://www.printables.com/model/673120-park-tool-thh-1-sliding-t-handle-hex-compatible-wr
The author remixed this model.
Added a new part to go along with the existing system
