Open Assistive Technology - Key Turner by ivan_gee

Last crawled date: 3 years ago

This is my own design of an open assistive technology device which allows people with missing digits and/or reduced digital dexterity or grip strength to insert and turn keys in locks.
For people with arthritis this device can be operated with little to no grip strength.
For people with missing digits and/or reduced digital dexterity this device can be operated with a minimum of one finger and can accommodate a maximum of three fingers in the device but you can obviously use you whole hand if you want.
The device can fit comfortably in a pocket and with the fluorescent color it lends itself to easy identification even in low light settings.
In addition to the 3-d print, I use one 4mm bolt, two 4mm nuts and one 4mm washer to secure a wide variety of keys within the recessed area of the device. Behind the handle of the key is a short slot which allows for keys with varying handle sizes and handle hole locations. With a small modification a key loop can be added so that it can be attached to a traditional lanyard or keychain.
I have personally tested this device as of 26 Oct 2016 and it works quite well if I do say so myself.
