These parts are designed to use a continuous and unbroken profile all the way up the part. Prusa and Slic3r call this vase mode, while Cura calls it spiralize.
I decided to build out some parts so I could print a camera mount with vase mode. I love vase mode and it seemed perfect for these parts. The thin walls allow for very good articulation between the sections and vase mode means they are still very strong.
Not sure if these would work in anything that didn't have some give to it (PETG and similar), but if you have good luck with other materials please let me know
General advice is to print slow, I typically shoot for about 10mm/s wall print speeds. The perimeters are pretty short so you want to give the PETG a little time to settle if you want to keep a nice clear part. You could run your fan higher, but it does cloud the print.
It takes about 13 minutes per part. I was able to print nine tripod sections in one setup on my MK3. The sections are 27.5mm tall and thus fit within the build volume of the MK3 when 'Print in Sequence' is selected and the extruder is modified to allow slicing. I did find that Cura had incorrect nozzle dimensions (probably from an older revision) and I had to bump them out to avoid hitting the already printed parts. In PrusaSlicer, this setting may be modified in ‘Output options > Sequential printing > Height’. As long as you're printing from front to back, you won't crash into the previously printed parts.
