Life-Size Door Opener

#### Life-size, Pretty Big and Strong Door Opener. On a daily basis, we need to open and close so many doors. The present design is a life-size ( within 137 mm x 120 mm) door opener that could be used to turn, push, or pull a door handle to avoid physical contact. It uses a bit of K-12 geometry. It is pretty sturdy. The rectangular handle provide decent protection for the hand. Also, it could be used as a handle to lift shopping bags or other things. This one works. But I think our students can design a better one. **This is not a toy. Please be safe and follow all local safety protocols!** #####Among the Files A and B are similar. The only difference lies in the positioning of the notches in the hooks. C has a handle perpendicular to the hook. #####To Print 1. Use a lower resolution (such as 0.32 - 0.40 mm). It does not matter much in this case. 2. Use a higher infill rate for strength. 25% works well in my testing. 2. Scale it down to 70-80% for a kids' version.
