Thumb Tack hook
thingiverse
I designed this with big tolerances ( 9.5mm thumbtack diameter with 2 mm Needle ) so I could print it with my 0.8 mm Nozzle at 0.3mm layer height. Thumbtack will fit perfectly inside the hole and will stick out the other side to hold the hook on a wall. Perfect for keys and for a baseball cap like what I use mine for.
