For the stripes to be exactly as in the photo set color swaps at Z = 15mm, 16.6mm, 19.4mm and 21mm (This is correct for all the models with h=25 the rest I haven't printed yet)
There's a groove at the bottom for filament to be pushed into, to make the plate not stick to the ground as much. Use the accent color for extra flare ;)
I used PETG for its greater UV and temperature resistance. Mixing white and translucent colors works nicely, but feel free to experiment.
Other settings to note
Other thicknesses, diameters and heights can be requested, or you can remix the model yourself here in Onshape
