Hi there. I'm printing the medium size pendulum clock, using Igus I150 filament. I hope this works. I will post the results here when I finish. https://youtube.com/shorts/ncmGd-MEEPY?feature=share

This is the 7.5 version running with 10 pounds. Maybe can run with less but I don't tested yet. It have 72+ hours running without issues. video here https://youtu.be/jHRajWgO9N0
