This is a rare type of print, it did not start out as an stl file, or evan as an openscad file instead all of its gcode is generated via python. The entire rocket is described only mathematically via algorithms written by Rylan Grayston. We did this to eliminate errors that may be part of the normal sliceing process. We have had great results! and the script generates ten thousand layers in about 1 second. more fun like this can be found on github: https://github.com/Rylangrayston/gcodeWriters all of our prints that you see here were done with the standard 100 dollar peachy printer kit. The rocket in the pictures is 10 cm tall and has 10000 layers. Like most peachy printer prints it has 100 layers per mm. NOTE: the scad file really just contains python... thingivers wont let me have only a .py file lol
