There are a few collections in the warehouse, but all seem to have rather large file sizes. This is a summary of basic shapes. Using nested components reduced the file size and still allows building detailed models.
(The pitch/grid is 8mm, the gaps/tolerance is 0.1mm; the bricks are (7.8mm + N*8mm; N=0; 1) by (7.8mm + M*8mm; M=0; 1; 2; 3; 5; 7)
