Most orchids require lots of air around their roots, and many, if not most, prefer growing in hanging baskets. There were not many available commercially, where most of the basket's surface would be covered by holes, yet holes would be small enough that some of the finer orchid mix particles don't fall through, so I designed one and had a few printed.

This was originally designed to fit 120mm x 120mm Panowin bed, but I botched the outer sizes of the resulting minkowski() shapes in OpenSCAD, and it came out a little too large for it (more like 150x150mm), so I have to scale it down to 70% in my slicer before printing. If your printer is large enough, you can print as is.

The size of the basket - width, length, height - as well as the sizes of the hexagonal holes are parameters in OpenSCAD that you can adjust to your needs. Some combinations of params may require manual adjustment to get the holes lined up right.

This basket uses chamfering (mostly for structural strength), and is using Chamfers for OpenSCAD library from here https://www.thingiverse.com/thing:1305888 but I included its file with mine because I wasn't sure how to properly include external module/library to make my .scad file renderable.
