Serious Clamp It Square ! (3 sizes)

If you build things, squares are a must have tool. What if, instead of checking if your works is dead square, clamping it directly to a square for a good result : first time, any time ?

You can't always find Clamp It Squares in your local store. Especially in Europe. And if you finally find some, serious models will cost you about 10 bucks each !

The Clamp It Squares I designed are actually available in three sizes : Large, Midi and Mini. They will be useful in various kind of jobs, from light DIY jobs to serious furniture making.

One last advice : don't over-tight the clamps, as the job is well done, no joinery needs extra pressure.

Edit : Added a new size : the Clamp It Square Mini, for smallest jobs, expecialy designed for spring clamps.

Edit : If you're looking for holders for your clamping squares, I recommend Gromax's holder for midi size: https://www.thingiverse.com/thing:3135812

Edit : added a beefy version of the Clamp It Square mini, by onlytobeking.
