stlconvert is a program that converts STL from ASCII format to binary and vice versa.

stlconvert automatically detects input STL type and converts it to the opposite type. Arguments are following:

$ stlconvert INPUT OUTPUT

Example:

$ stlconvert input-ascii.stl output-binary.stl

On Linux, simply call make. After that, you can use stlconvert that was built in the repository root:

$ make
$ ./stlconvert
