This is a replacement mounting bracket for the popular 150mm wedge style rain gauge sold under several brand names including Nylex, Holman, Neta, Greenleaf and many others. I found that the original bracket was not very UV resistant and disintegrated inside 2 years.
The bracket should be printed in PETG, ASA or some other UV resistant filament. Snug supports are recommended under the retaining lip, these are easily removed in one piece without leaving blemishes.
Other print settings used:
0.2mm layer height
3 top/bottom layers
15% infill (Gyroid)
