This is a handy hook to be placed on the top of a door. The current version suits a 35mm thick door and is meant to enable the user to hang a few items of clothing. I have found that up to two hooks can be used on one side of a door if these are being utilized for clothes hangers. They are thin enough to allow the door to close without impediment - Naturally this depends on the door type and how it is hung so I suggest that a test item be printed first to confirm that the design suits the door.
The hook was originally printed with PLA and has proven strong enough to hold a couple of kilos easily.
