Gridfinity holders for extra-long 3/8" drive hex (Allen) bit sockets, with versions for both Metric and SAE sets.

These trays were modeled around the CASOMAN 3/8" Drive Extra-Long (Ball-End) Hex Bit Socket Set (18-piece) with both Metric and SAE sizes.

Fit notes / compatibility

• Built to fit “extra-long” style hex bit sockets with a similar overall profile to the Casoman set. 
• Your set should fit if the sockets are close in diameter (approx 18mm body/attachment diameter as a rule of thumb).
• If you’re unsure: measure your largest socket OD and compare to the pocket size before printing the full tray.

If you print it
Let me know what brand/set you used—especially if it’s a non-Casoman set—so I can add confirmed-fit notes.
