This is a Gridfinity 3X2 socket holder that holds up to 9 sockets that are approximately ¾ inch in diameter. This holder is designed to fit the Carlyle Socket Set 3/8 in SAE (1) 9 Pc Set MPN: 610219 or NAPA PN: NPT 610219 https://www.napaonline.com/en/p/NPT610219. This bin has the standard magnet pattern on the base since I am using these in my tool box. 

I have uploaded the Fusion files as well as STEP and STL incase you want to modify the holder. If discs do not fit it should be fairly easy to change the dimensions to fit different thickness sockets or change the text.

The Base for this model was generated using the Fusion 360 Gridfinity plugin from Lev Mishin. For more information on this plugin check out the github and the Autodesk plugin page.
