Marble Run 003 Kit Help

Anyone here who has printed these “belts” for the Marble Run Kit, who knows how to print them? In my test it was completely stiff and wouldt move at all or put them together at all.
Any suggestions to anything i should change or something?

I used Sunlu PLA and they were hard to move when i removed them form the plate however after a while of moving them back in forth they did loosen up. I also need to use some pliers to snap the links together. Mine was printed on the A1 with standard profile settings.

What filament are you using? What printer?

I had no problem at all with printing these “belts” using the Bambu printer profile. The only challenge I had was to attach the loose pieces together.

Filament: PLA on P1S Combo

I was able to successfully print them with Basic PLA, I did .012 layer height preloaded print profile and they turned out great.
