The author remixed this model.
I really like the "Gridfinity Screwdriver Stand" from @Beamsjr but it was to big for my screwdriver set. So I just cut the legs a little bit shorter. The Metal part of my Screwdrivers is 50mm which is the maximum size which will fit.
You have to print the base of the model still from the original model. Then you can replace the upper part with my design
