See all my Gridfinity designs here

Gridfinity trays with a wider than normal rim/border (4.75mm).

Sizes range from 2x1 up to 5x5.

These are designed to press-fit magnets into (standard 6x2mm).

There are two print profiles:

1. A standard version with 2 wall loops. This is a quicker print, but if you care, in a bright environment light shines through the walls, and you can see the infill pattern easily. Doesn't matter in a drawer or dark office etc.
2. Thicker walls (5 loops) so that light doesn't shine through, but longer print time.
