It should be possible to do this with modifier meshes, but it would require manual work (since you have to position the models yourself).
There isn't a way to change the order in which it's printed as far as I know.
As the timing belt I need is the smallest timing belt ever ( 1mm pitch ), it doesn't have and doesn't need a cord inside. I already cutted one and they are 100% polyurethane. Also, the mechanical force are limited, as load and speed are really low.
I succeded in printing one ! This is a first try but I am much more confident to print a usable one.
What do you think about it ? How can I improve the rack shape ?
Thank you very much, I'm building my own printer. And this fits. I'll let you know when I'm done. And I will praise you everywhere. If I ever do a workflow. I will definitely publish you. Thanks a lot👍🤝
Just a note. On that cooling (ribbed part). There is a cut. Just about the strength of the bottom material?
