Remixed my first Fusion 360 Model to hold a Craftsman set of SAE 3/8 Hex Bit Sockets I found buried in my tool chest.
Holes were sized at 16.75 mm in Fusion 360 as this results in a 16.5 mm when Printed on my Ender 3 V-2 Neo. This seems to hold the socket securely to the point that I can turn the holder upside down and only two will fall out.
Your mileage may vary as my Hex Bit set was purchased a few years back.
Mine are printed in Black PLA and I use a silver Sharpie Pen to color the numbers.
Thanks for looking at my Model and if you decide to print it out I would love to see a photo of the results and your feedback if there are problems.
Also thanks to the creators of Gridfinity as its a great standard to build a tool organization system on.
The author marked this model as their own original creation.
