I liked the original model as a neat holder for my ¼" sockets. But with 16 slots it was to large for my Wera Zyklop Belt. Therefore I reduced the number of slots to 12, keeping the rounded edges and the original hooks.
To hang the tray to your Skadis Board you need 3 hooks from the original model. They are a tight fit, so be careful when installing them. I used a plier to press them in place. You can add some glue but I don't think its necessary.
The author remixed this model.
The number of slots for the sockets is reduced to 12. 3 hooks required for hanging.
