This is planet mars generated using a slightly remixed script provided by uwezi. The modification is to impose a wall width as float number and also an extra rule for limiting shell tickness to max 2*wall (for relief). This will spare filament, speed up the printing and also provide better illumination when inserting a lamp. Modified script is also provided.
A 150mm rendering is included and was generated with this command, based on the attached bumpmap (also provided in the original object).
python gen-relief.py -s Mars2 -d 150 -w 1.2 -f 200
Recommended to to split into two parts for easier printing (preferably in a bottom part to minimize the possible visual impact gluing the parts)
