Yale Thumbturn grip

thingiverse

If you're struggling to turn your Yale thumbturn lock because it lacks grip, this solution might just do the trick. It slides snugly over the original thumbturn and can be easily pushed straight on. The design is printed in two pieces, making it simple to quickly assemble using superglue, also known as crazy glue for our American friends. This innovative product was created with the help of Tinkercad's user-friendly 3D modeling software.
