Parametric watering can rose

The diagram shows the parameters that can be changed in the spreadsheet of the Freecad file. Notes: I printed these using a 0.4mm nozzle, which limits the hole size to about 0.9mm. I recommend 1mm. After printing, use a pin to clear any blocked holes. I have blocked off the bottom holes to help prevent dripping. After choosing hole size, number of holes and spacing, look at the rose face and check that the holes aren't obstructed by the edges. The default angle of the face is to align the spout with the lower cone surface. I have found this reduces dripping. The rose is designed to be use pointint upwards, which takes a little practice. See the video below. The wall thickness is 1.5mm apart from the role face, which is 1mm. Measure the spout diameter of your watering can accurately using a vernier gauge. Use silicon grease if there it leaks. I have used PETG for strength and water resistance. You will notice that the smallest rose dripped. This one needs 1mm holes far from the edge. Th
