Quick 5min design for a simple hook.
Base is 20mmx20mm (many double sided tapes are 20mm, so perfect fit)
Goal was a sturdy design which also allows easy and quick printing, that's also the reason for the slightly asymmetric design.
Takes 20-25min to print depending on the print speeds and settings
