Napier Bones

thingiverse

This thing draws inspiration from https://www.thingiverse.com/thing:577834. The same tables were used, but the remainder of the code was re-implemented. The main differences are: - Smaller and therefore faster printing, - Using a real font instead of recreating number characters, - Embossed numbers that work somewhat better for vertical 3D printing, - Fewer magic values in code and better parameterization, making scaling easier, - The bone number is printed on top, making them more easily identifiable. This file can generate STL files for all ten bones. Simply uncomment the desired bone function. Printing with a 0.4mm nozzle and 0.20mm layer height was found to be acceptable. However, smaller sizes will improve quality. Further optimization of the code is possible, but optimizing the result is more interesting. The txtHeight parameter, which represents the actual depth of the numbers, works best when close to the actual trace-width or nozzle aperture. The separators are not very prominent and could be improved. https://en.wikipedia.org/wiki/Napier's_bones
