T-Bar 8mm Square Panel Key

thingiverse

This is a custom-made, square-panel 8mm key that's designed to unlock a wide range of metal locks. The key features a sturdy T-Bar handle that provides a secure grip and control when turning the lock. The bar itself measures 7.8 x 7.8mm in size, giving it enough room for additional printing material to be added without compromising its functionality. This extra material ensures the key remains useful even after repeated use. To create this key, I used a high infill setting on my 3D printer. This approach was necessary due to the need to open stiff metal locks, which often require a bit more force and leverage than standard keys can provide.
