I ***led this file "Bird Poop Preventer."
Tired of the birds clogging up our rain gauges, this is version 3.0 or there about. First version was a plywood circle with the same spike strips screwed to it. That first version was mounted to the post that the rain gauge was on and made servicing the rain gauge a little more difficult. This one being attached to the rain gauge should make servicing simpler. Two thumb screws, and about an eighth of a turn of the cylinder, removes the entire cylinder, and the spike strips come off with it.
Creality PETG, some McMaster Carr hardware; stainless self tappers, 10-24 thumb screw, and and hot melt threaded insert. The bird spikes are some random Amazon offering.
