: 3D PRINT 18 parts: print every part six times

original size need a 230mm X 230mm printbed so on Ender 3/5 or bigger it is possible

optimized for 1mm nozzle because of overlap within the print min. 0.8mm nozzle

In Prusa Slicer use spiral mode or 1 line on the outer and a lot bottomlayer with 0 infill and draw the vertical seam on one edge for slicing

can recommend PETG, oktoprint with klipper and a Red Lizard V1 hotend with highflow so i print 18 parts in around 34 hours for one ring

i used foldback clips to join the parts together

: CONCRETE: cooking oil works also to separate concrete from petg parts

use water-resistant concrete if used in cold areas

AND i use a steel chain in the middle, can prevent apart-breaking.

: PLANTS : not every Plant will work can recommend small plants

use a big trivet with 34cm radius to protect the WuuYA Tree from ants and snails with a moat/ring of water
