These are standard 6U gridfinity bins that I use in my storage boxes and toolbox. They have holes for 6mmx2mm magnets. 

These are very basic bins… there are some amazing ones out there that are lightweight, have snap in labels, etc. 

These are for here for convenience but there are some awesome generators out there: 

• Perplexinglabs
• Gridfinity Extended
• Spacerless

The most important part about generating a bin is getting the 6U height and making sure that you have the stacking lip with a 4.4mm depth of stack, as per gridfinity standard. 

Gridfinity was started by Zack Freedman. Gridfinity was inspired by Alexandre Chappel.

These were modeled from scratch.
