This is so awesome, thank you for sharing these details. 🙏
No doubt in my mind that you should obtain a printer if you're planning to assemble that many units. It shouldn't require a deep dive into 3d printing to just get some enclosures printed though, especially the Open Pill. That was intentionally designed to be a single, simple print and not to require *any* additional hardware to be able to build a signer.
Please be in touch if I can help and would love to hear more once you get some of the signers built and deployed.
