I was curious about the “flexi world” since I had never designed one before, and I've only printed a few as gifts. So this time I decided to give it a try and make a shark (which seems to be a classic). I also added a hole in case anyone wants to turn it into a keychain.

About the print
I did three  tests with the single color version, both with and without supports, and both printed successfully. Also at 70% scale

I also printed two multicolor sharks. In my case, the colors mixed a little (black and light blue) because of the purging volume setting. I had it set to 0.6, but I updated the print profile and set it to 1. 

I'd recommend doing a few tests if you're using colors with strong contrast like I did!
