Here is my take on stackable Gridfinity storage !

You can find 4 version of this model :

1. 1x1 Gridifinity Size, with 3 Bins
2. 1x1 Gridifinity Size, with 4 Bins
3. 1x2 / 1x2 Gridifinity Size, with 3 Bins
4. 2x2 Gridifinity Size, with 3 Bins

For each model you can find the Lid that snaps onto the outer shell (outer bin) which you can slide each bin into. The outer shell is 9 units tall without the lid added on top. You can also print the label which you can snap onto the Lid using 2 notches back and front of it, do not forget to face the 2 triangle pairs for alignment. And a sticker measuring 30x50mm or 30x30mm can be placed underneath it to keep track of what's inside. 

To achieve the best contrast, I suggest using the color scheme provided by the 3mf files.

Print Profile : 

• Layer Height : 0.2 mm
• Use Arachne wall generation
• I recommend ironing the topmost layer of each bin for better number visibility (60mm/s, 30% flow)
• Support : Only needed for the "Lid" AND On build plate ONLY( Normal Grid Support Recommended)
