+A stackable sorting sieve for bricks, nestable for storage.
+You will need to export all 5 levels, to get a full sieve.
+If you feel you do not need the upper levels, just do not export them.
+x,y,h are the dimensions for the largest sieve,
+they will be the outer dimensions of the box,
+the smaller sieves will be nested inside, therefor smaller.
+Of course 256mm or 384mm (base plate size) are recommended values for x and y,
+but you can use any value you like.
+
+Full set of all 5 levels:
+
