Custom purge towers in Cura

[avionne 0]

So, purge towers. They love to break. Every time I've done a tall print, the tower always fails, making the part extremely ugly and introducing a looooot of post processing time. I have tried to make the tower diameter thicker, increase the minimum volume, etc. At this point, I do plenty of prints without the tower but I would still like to have one.

 

Has anyone figured out a way to make a custom prime tower in Cura? Currently my approach is just importing 2 stl's of my own towers (one for each material) and then importing my actual part. Non-uniform scaling allows me to adjust the z-height of the towers to the height of the part.

 

However, I just can't figure out the order in which different objects are printed in the same layer. The ideal order would be model tower, model parts of the thing I'm printing, support tower, support parts of the thing I'm printing. Is there really even a way to do this? I'd appreciate any help 🙂
