simple measuring hook

That's my second version of my mesauring hook. No scale but the tape mesaure is way more close to the working piece. So you can mesaure more precisly. Furthermor I added an other angle: Now you have: 45° - 90° - 135° - 225° .
Have fun.

also look at my other more versatile version with scale:
