and added a little notch to jam the movement a little - edit: and Thank you for your Feedback! (edited)
@LoboCNC i just noticed this too, this was a result from the steeper angle, also the hole was moved for stability - but with the end stop the force is now not levered against the wall - so if you check you find the MK Ⅲ with a slot so also adjustments are possible. You could add a little grease so the movement is retarded , if mounted on a wall it shouldn't move by itself - but i can add a little notch to keep it closed
Very stylish hook, and easy to print. Just a couple of suggestions: a screwdriver needs to go in at an angle to access the mounting hole, but it looks like there is plenty of room to move the mounting hole up a little. Also, it flops pretty easily and could use a spring or friction catch to hold it closed.
