This is a Crochet Block Set. e.g. for blocking Granny Squares.

I printed the tileable Plates, slided and glued them together (glueing is advised since the connections are fragile). A second Set of Tiles is good to fix the Sticks at the Top.

I also provided a large Plate so glueing is not needed.

The thin Plate can be used if you stack many Grannysquares to prevent the bending of the Sticks.
