I attempted to build a small try-square, but my metal working skills totally suck. I tried to flatten the metal blade with a file, but I didn't reach my own goal. It's not perfectly straight. The square is almost 90°, it shifted a wee bit when drilling the holes for the pins. Also, the blade is 0.1mm off of being parallel. I have to try again or simply just buy one.
