Hi everyone! I designed this ergonomic key turner to help anyone who struggles with turning standard keys due to arthritis, joint pain, or weakened grip. It transforms a tiny, slippery key into a massive, comfortable handle, allowing you to use the strength of your entire hand and arm instead of just straining your fingers.
To make it accessible for everyone, the project includes two distinct versions:
Glue Version: A completely hardware-free design. Just place your key inside and glue the two halves together. Perfect if you want a quick print without buying extra parts.
Screw-Reinforced Version: Designed for maximum torque and heavy-duty locks. It features precise cutouts for standard M3 nuts and screws to mechanically lock the halves together.
Features:
Ergonomic Design: Large, rounded profile with generous fillets that fit perfectly in the palm of your hand.
Alignment Pins: Built-in pins ensure the two halves align perfectly during assembly.
Internal Key Lock: A central alignment pin and a tight inner pocket keep the key securely locked in place, preventing it from slipping inside the housing.
Bill of Materials (for the Screw Version):
2x M3x10mm screws (Button head or socket head)
2x M3 hex nuts
Printing Tips:
Material: PLA, PETG, or ABS/ASA for extra durability.
Perimeters: I highly recommend using 3 to 4 walls/perimeters to ensure the screw holes and the inner key pocket are solid and don't crack under torque.
Supports: None needed! All parts print completely flat on the build plate.
If this helper makes your daily life (or the life of your loved ones) a bit easier, please consider leaving a like or posting a photo of your print! Happy printing!
