Schaller Guitar Strap Lock Wrench

thingiverse

I keep losing my strap-lock's grip due to the constant loosening, and I never seem to have a wrench nearby to tighten it back up. That's why I created this tool - it stays right with me inside my guitar case at all times. This device consists of two main parts: a lever that holds the nut in place at any desired angle, and a socket wrench for making those necessary adjustments. The lever cleverly stores within the handle itself, ensuring both components remain together whenever I need them. Check out the accompanying pictures to see exactly how this tool works its magic. Its design is tailored specifically for my Schaller Strap lock, although it should also fit 13mm or 1/2 nuts from other manufacturers without any issues. If you've built one of these tools yourself, please share a photo with me! I'd love to see what others have created and how they're using this handy device.
