When I wanted to transfer my current toolbox from tecpo with a lot of SAE sockets and wrenches I found the gridfinity system. Because I did not find suitable boxes which are fast and easy to print with a minimum amount of material I designed my own. 
Specially optimized for this imperial Tecpo socket toolbox. 

All boxes fit onto Gridfinity baseplates. 

Key Features

• Filament and print time savings: This holders are no boxes but only shells
• Gridfinity compatible: Designed from official Gridfinity specifications
• No Support needed: Chamfers have 45 degrees
• Easy to print: No letters on top or first layer (but space for labels)

Print Instructions

I designed them to be printed upside down so the upper side of each box is touching the buildplate. In this orientation I designed all angles to be printable without support. 

I printed them with 

• PETG
• 0.6mm nozzle
• 0.3mm first layer height
• 0.4mm layer height
• 10% gyroid infill
• 2 perimeters
• 3 bottom, 3 top layers
• No supports
• Top of boxes on print surface
