@MallocArray thanks for sharing but to be honest I am not sure what to think about a project selling built instructions and at the same time claiming to be open source. I think it’s misleading.

It is an interesting choice of words. The firmware itself is fully open source and on the Github page. It is only the instructions and STL files that are for purchase. I haven’t seen that mix before to try to have some revenue from the project, while not entirely gating the project behind a paywall.
