Adjustable Shelve Hook w/ Flippers

This is another remix of LerouxB's cube wall hook. This time I've added flippers to the design and shortened the hook to help stabilize the hanging item in case it is bumped into and/or is being pushed by wind (This was my problem).

The hook is pretty flexible when it comes to changes to its measurements. For printing, infill density of 20% recommended to keep the hook strong despite its thin size.
