The "Impossible Dragon" by dreggory was the exact kind of tensegrity figure I searched for, but I wanted to print it without support where possible to get the best possible finish. Therefore I cut it in FDM friendly pieces which need only minor cleanup.
See 3mf files with Prusa Slicer for print setting details and used modifiers! If you have a Prusa i3 MK2 printer, you might be able to use them even without modification.
I printed it at 150% scale and used CA glue to assemble the dragon. For connecting the thread to the parts, I recommend this order using a tiny drop of CA glue:
Cut 4 pieces of thread, longer than needed at first.
Glue the 3 outer ones into the hole of the base.
Glue the middle one into the hole in the tail of the dragon, not the base!
Start positioning the dragon above the base by estimating the length of the outer 3 threads, use pieces of tape to hold the yarn in place at this step!
Thread the middle yarn of his tail to the hole in the rock and lightly pull on it to make him "fly" and check the 3 outer yarn lengths. Adjust if needed.
Fix the 3 outer yarns to the dragon with a drop of CA glue, wait until dry then cut the excess length and remove the tape.
Lightly pull on the 4th middle yarn for final check and lock the yarn in possition with tape.
Apply a small drop of CA to the yarn in the rock, wait until dry, cut excess yarn.
Enjoy!
