I can take no credit because I merely combined the great works of smysnk and alexandru-hauzman in PrusaSlicer and uploaded it for your convenience. The STL parts are partly overlapping so make sure your slicer doesn't get confused. PrusaSlicer handled the multi-color print without a problem for me.
I printed the first layer at 0.2 mm height and the rest at 0.15 mm. The droplet symbol is 0.35 mm high.
