I’m impressed. I’ve got a inkjet that Is about 18 years old. I have to occasionally wipe off the print head, but otherwise has never needed repairs. The ender 3 we have has needed replacement parts from heads to hot ends and feeders, and every print requires specific to it setting. I can print to my hp using generic drivers without a second thought. 3d printers are far from that level of ease of use/ reliability. I’m glad your stuff worked, but that’s the minority.

It’s possible that we could reduce regular use, yet allow those with accibility issues to continue to use the alternative. This can work in tandem to help address the real problem accumulation of single use plastics. Not using a straw is a valid solution for the majority of use cases.
