About this 3D model
I have a nano tank I am building, and floating plants on the way I want to keep corraled once they arrive. Worked up a quick feeder ring in Fusion360, checked to see if it'd float and stay watertight and all is well. Printed in clear PETG, 5% gyroid infill, .2 layer height, 3 walls. Comments report PLA works also. ## Addition, small hack ## To avoid supports, drop the bottom just a tiny bit under the build plate in the slicer. this forces it to print an entirely flat bottom. A very small amount is needed, the ring will finish rounded but with a flat bottom surface, thus eliminating any supports.
