Printer: Ender 3 Resolution: 0.20 mm Speed 50mm/s Material: PLA Nozzle Temp: 205°, 210° on the first layer Bed Temp: 55° Infill: 10% Walls: 3 Top Layers: 4 Bottom Layers: 3 All parts were printed in PLA and are straight forward prints with no supports. However, for the top sheet, in order to obtain a smooth polished finish, you will need to print onto a glass bed. I used supports on this part to bridge the gaps between the hexagons but this may not be necessary. Make sure seam position is set to "aligned" or "rear" [Prusaslicer] when printing the base. Do not use the "nearest" option (as I did), ugly lines will appear around the base.
