Specifically designed for the model of Command hook shown in photos. I believe its sold as a Large Double Hook 4lb.

Command hooks are very useful, but I swear the plastic plate they give you must be a planned obsolescence scheme. Over time, it cracks and breaks in a very predictable manner. I've had two break so far. Instead of spending $10 to buy a whole new hook kit to replace the plate each time, try this printed version!

Recommendations

• Print on side to ensure layers aren't sheared apart when in use.

• Use automatic supports on build plate. You may need a sharp knife to carefully remove the supports from the rail guides. Test the rail fit before mounting to your wall.

• In theory, the lower the print height, the smoother the back will be and the better it will adhere to the Command strip. I have tested 0.15 and 0.25 and both seem to work well though.

• Set perimeters to something high, such as 10. There should be no visible infill in your slicer; just outer layers.

• Use this at your own risk! I don't want to be responsible if the hook falls and breaks whatever you were hanging on it. I have tested multiple prototypes, but I have not tested this long-term so as far as I know it could fail in the same manner as the original after some time.

Features

• Guides to attach to the hook's rails. [Photo #4.] This makes the hook much more stable and less wobbly from side to side.

• Indents on top and bottom to conceal pull tab more easily, especially if you're using two Poster Strips like I am. [Photo #5.]

• Lift-stopper similar to Command's original design, but larger and rounded for easier printing.

• Grooves and center support just like the original design, but thicker and [hopefully] stronger.

• Much larger and stronger center mount.
