4 kitchen knife holders designed to fit into the gridfinity system. Two are 9x2 squares for larger knives, one is 8x2, and the other is 7x2. There are files for each that are cut to fit onto the build plate of 180mm x 180mm printers,  such as the Bambu A1 Mini and the Prusa Mini. 

The 7x2 has spots for 2 chef knives up to 290mm long, and a utility knife.

The 9x2 has spots for 2 or 3 large chef knives up to 370mm long. 

The 8x2 has spots for 3 chef knives up to 330mm long. 

Update 24 Feb 2024 - Upon request, I added a 2x8 knife block.

Recommended print settings are 3 perimeters, 4 bottom, 5 top layers, 15% infill.
