Crocheting requires repetitive wrist rotations for extended periods of time making it difficult for those with wrist arthritis to take part in this craft. Currently there are no crocheting devices on the market that assist with these repetitive motions. A comfortable crocheting device that reduces the need for wrist rotation could benefit these users with wrist arthritis. We designed and fabricated a 3D printed device with a spinning disk mechanism that rotates the crochet hook when the user activates it with their thumb. For added user comfort a silicone rubber hand grip was cast to slide onto the handle of the device. Multiple hook sizes are compatible and interchangeable within the mechanism so users can use one device for many projects. The device limits wrist rotation, is small and lightweight, and can be effectively used to crochet. With these attributes our crocheting device will aid users with wrist arthritis.
