Screw on removable shelf hooks

UPDATE: I have added 3 new brackets with 28mm, 35mm and 45mm throats (in addition to the original 23mm) If you want to hang something from a shelf, but you do not want to screw a hook into the wood and leave a hole then these removable shelf hooks are ideal. Fits shelves 15 - 22mm. A little superglue is required to assemble. Each shelf hook comprises of a body with a screw in adaptor. The centre of the screw is hollow to allow a pin and hook to be inserted. The complete hook is designed so that the hook itself will rotate until it's tightened on the self allowing you to orient the hook as required. They then can be installed and removed in seconds and reused. These hook are ideal for workshops, kitchens and for temporary occasions where you might want to hang something up like birthdays and Christmas. There are 3 versions of the pin and hook, all of which fit the same body and screw.Pin and round hook. The round hooks require supports to print correctly and may require a little tri
