This is a module for openSCAD that creates films spools with a varying amount of sockets. It was inspired by mlagana's spool but completely redone.The included STL has 8 sprockets but using the scad module spool() with a parameter will generate a spool of a different number of sprockets. Because of the spacing of the film holes changing the number of sprockets changes the circumference (and radius) of the spool.
