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
Use a lower resolution (such as 0.32 - 0.40 mm). It does not matter much in this case.
Use a higher infill rate for strength. 25% works well in my testing.
Scale it down to 70-80% for a kids' version.
