[Update 1 Jan 2021] STL files updated for better rigidity at the front ends. Video available: https://youtu.be/aUt2ugDGjiU [Update 12 Aug 2020] STL files updated for improved mechanism, accuracy, and printability. [Original post] I've used this for a month without it breaking, so I'm sharing it with others who might like to try it too. It's the result of multiple design iterations after weeks of work (as shown in one photo). This multi-functional tool fits my needs for going out to work, and its sliding design keeps any viruses inside if touched. Its functions include: 1. Door opener by holding or pushing the door knob/handle. 2. Wine glass holder (yes, I need this). 3. Lock knob twister. 4. Press for switches, keypads, or any buttons. 5. Thick/thin pen holder. 6. Paper tweezers useful for handling office paperwork. 7. Key holder. 8. Rod holder. Its maximum open is 37mm wide, enough to handle most door handles. The design is well-optimized for ergonomics and is very handy and efficient to use. Note that when using it as a handle holder, you need to work your index finger with the slider (as shown in the photo). This design choice improves durability and operation efficiency. The slider is purposely designed to be loosely mounted on the base, allowing effortless sliding and tolerating 3D printer accuracy issues. You can remix it for a tighter fit, but I've enjoyed its looseness for fast operation. When printing, orient the two items in the same way as shown in the photo. No support is needed, but you may want to use 'brim' to improve adhesion if your printer has common problems with small bases going high in print. This design is not scientifically or governmentally approved, so use it at your own risk. Share your experience and suggestions for improvement!
