OpenSCAD Optimized Parametric Honeycomb Module

SummaryThis is an openscad module to generate an ideal honeycomb pattern for 3d printing grilles and drain covers. If you need to add drainage or ventilation holes to your project, or just want a really cool honeycomb grille pattern, this openSCAD module should greatly simplify the process while ensuring the strongest possible printing conditions.To use: simply difference() the object you want perforated with honeycomb_pattern(width,depth,height). Optional parameters include wall_count for the number of printed walls that each line of the grid should consist of and $print_wall_thickness (set to match your printer nozzle or wall extrusion thickness setting) or wall_thickness if you want to specify it manually (but might not print in the strongest and most ideal manner) as well as edge_length which defines the size of the honeycomb pattern based on the length of one edge.You can paste this into the beginning of your code, or add it as an include to your project library.
