Fence for gravel next to drain - Version 2.0

thingiverse

Version 2.0 This is version 2.0 of Fence for gravel next to drain. I improved the appearance and also the rain throughput. Intro I do own a garage with a flat roof. In order to protect the roof from UV light coarse gravel has been put on top. The gravel shall not congest the drain, hence I designed a small fence. Printing Printed in PETG with 3 perimeters. Also, the tubes have 20 perimeters so that the they are printed in circles. Printed in white as the fence is exposed to heat especially on the garage roof during summer time. OpenSCAD The OpenSCAD file has been provided. Disclaimer Please use at your own risk. The fence has just (August 2022) been installed on the roof. I have no experience if a) the fence will allow enough rain to pass through under heavy rain conditions b) the fence is strong enough to keep the gravel away from the drain c) the fence lifts after some rain because it is printed with 20% infill. This might lead to gravel falling into the drain and congesting it d) the PETG will melt in very hot summer scenarios
