[SCAD] Customizable Atrium Drain Grate (with drain gaps)

thingiverse

UPDATE 2024-11-17: Consider an improved design at https://www.thingiverse.com/thing:6834442. It is customizable, via PythonScad (a fork of OpenScad).This design had two flaws: (1) There is insufficient surface area to hold debris, and I had to clean it once a day whenever it rains (2) The rim/lip means there is a thin layer of standing water as debris accumulates. The improve design solves both of these problem with a larger surface area and a honeycomb pattern to ensure every water level has some direct flow to the drainage.Why did you make thisThis is a remix of Milkdog's "Customizable Atrium Drain Grate", but with drain gaps on the disk base.My drain does not have a dip, so the base sits flush with the floor. I needed gaps on the disk to drain water away to avoid pooling.Instead of filing gaps down, I customized the openscad to have a configurable number of gaps between spokes for draining.What is configurable?NOTE: thingiverse's Customize button does not seem to do import STLs as components. You must use OpenSCAD if you wish to tweak dimensions.The OpenSCAD file has a new variable named num_drain_gaps in which you can control number of drain gaps. The image and sample STL has it set to 6.For best results, select num_drain_gaps that are small divisors of num_spokes.Some best-effort fuzziness was implemented to align gaps to be between spokes as much as possible. It works well when num_drain_gaps that are small divisors of num_spokes.
