printable square ruler with guide and cutout (try square)

thingiverse

Just a simple square ruler with guide and cutout in the corner, so it can be easily used for marking metal or wooden parts (see first photo). In German such a thingy is called: Schlosserwinkel. I just learned from yvans comment below that in english this is called try square. The second photo shows both the printed ruler and the original metal ruler which inspired the design. The guide can be used to align the ruler with the edge of the work piece. At the base of the guide there is a small groove, so the guide aligns well with the edge of the work piece. Additionally, there is a cutout in the corner of the ruler, so it aligns well when measuring against two sides of the work piece (for measuring right angle). Well, just after publishing, I notedhttp://www.thingiverse.com/thing:143605 which has been published only a few days ago and which I hereby give the link to. However, I created my scad code from scratch using the existing metal square as inspiration. Instructions The photos show a ruler with 50mm long sides. It was printed with 3mm PLA filament at 0.4mm layer height, 2 perimeters, 25% infill. The scad file supplied is parametric, so you can customize your own ruler. The stls supplied are for 50mm and 70mm rulers. Both versions are also supplied mirrored. As you can see, my current filament is not the best.. After printing, it might be advisable to sand the sides a little bit, particularly if the bottom layer was squished a bit and protudes at the edges.
