These fit Gridfinity bins INSIDE. The outer base of this container is flat and does not fit into Gridfinity. 

The print profile includes a few 4x4 bins, but your best bet is to download OpenSCAD and customize your own boxes there. 

I kept running into issues with the original file, hitting a 200,000 element normalization error on larger 4x6 boxes.

This update rewrites the wall pattern modules and adds two additional options, Triangle and Diamond

Tested and working with large 6x3x12 baskets. 

------------------------------

Differences of the remix compared to the original

• Modified: hex_pattern — rewritten to use linear_extrude + 2D circle() instead of 3D cylinders; fixed tiling math and added boundary clamping 
• Modified: grid_pattern — rewritten to use linear_extrude + 2D square() to fix the 200k element CSG error; added safe_r corner clamping 
• New wall pattern: diamond_pattern — staggered rotated squares 
• New wall pattern: triangle_pattern — alternating up/down triangles with row stagger
