This is a holder for a mini blowtorch to fit on an Ikea Skådis board. The tool faces you so as to occupy the minimum board real-estate.
You will probably need to print with supports for the hook part.
The hook exists as a stand-alone part to integrate in your own designs here: https://www.printables.com/model/646625-skadis-skadis-hook-part/
The author marked this model as their own original creation.
