Socket adapter/converter holder

Made this because those converters usually get lost everywhere...
Now i have them on my tools wall in the garage.

Sizes on the holder is:

1. 1/4"
2. 3/8"
3. 3/8"
4. 1/2"

But should be easy to modify for your own needs if needed.
Printed mine in 30% infill and that is more than enough.
