I found that for some of my heavier tools the 2 hooks on the original were not enough. I have added slots to glue in the Skadis Hooks by Ryan Plourde. I also wanted to be able to print the model without supports for the hooks.
You will need to print 2-3 of the hooks - https://www.printables.com/model/745236-skadis-hook-attach-to-anything
The author remixed this model.
Added slots for Skadis Hooks
Removed original slot for hangers
