Wonderful manufacturer with very timely communication and shipping. I don't know enough about additive manufacturing to comment on best practices and techniques, but the case I ordered (from another developer's design) fits my Pi B3+ w/ PoE HAT perfectly.

Ответ: Thank you for the review, I look forward to serving you in the future!
The owner Jeff Hearrell was very helpful, he was able to help me modify the specs of my 3D print in order to make it more cost effective. I will most definitely be doing business with him in the future.
