This repository contains precompiled fillygon geometries as STL files. There are (at the moment) three different top-level directories, each containing 36 distinct geometric models like triangles, squares, hexagons, various rhombi etc.
Each geometric model exists in four specific flavours: normal (just the frame), with the area filled, with corners, and filled with corners.
In total, this repository contains 432 ready-made STL files for 3D printing. Recompilation of all OpenScad fillygon source files takes several hours.
Slicing the STL files to generate the printer-specific G-code representation suitable for your 3D printer at hand is a standard process. The Cura software does a great job here, its use is straight-forward.
Try the 0.25mm files first. If the hinges are too tight or loose,
try 0.4mm or 0.20mm files. Which version works best can also vary
across the exact kind of filament used.
