Woodworking square

This is a simple square to check squareness on my tools around the shop. There are two versions, one with holes for 12x2mm magnets and one without them. The magnets I used can be found [here](https://www.amazon.com/gp/product/B07GX7Z4DF/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1). I used superglue for the magnets.


The square is designed to be thick at 20mm. I find this is better for checking square on tools. The length of each side is 111mm or 4.37 inches.

I printed it laying down on its side.
