I've lost interest in watching his videos due to the new direction of the marble machine. I enjoyed the previous one as an art piece but then Martin got obsessed with perfection and turned it into a soulless bland engineering project with a frustratingly poor understanding of engineering.

Oh he is STILL at it? Wow, that's 5 years? Or more? Gotta give him this: he's persistent! I watched him at first, even if it's infuriating at times, but eventually even I lost interest, and I build shit like that myself. No marble machine, but giant mechanical calculators, a pneumatic organ, boats etc But I think that's what happens when musicians fabricate stuff. I know one who builds his dream guitar for 16 years. Next year he'll be done. So he says. But then again, so he says for 15 years.

Any idea what filament he is using? I'd like something like that

*Marble Machine 3. The Marble Machine X was the one that Martin cancelled.
