[SGVHAK] Working on projects + continuing hackerspace discussion

[Tux Lab]

The web interface is just a front end to pass the 3d stl file to a
back end parser that will check the 3d stl file and prepare it for 3d
printing.   If the back end process is successful it will output the
result back to the web server for user confirmation.   If the back end
process takes a while, we can email the user for confirmation.

For a while I was thinking of offering laser cutting service.   I got
as far as using rails to parse a svg file into its line component for
time/cost estimation and kind of stopped.    Parsing the svg file was
fairly fast, less than a second.   Theoretically, once the svg file is
parsed the web server will display the time/cost estimation along with
the original svg file for user confirmation.    3d printing is more
complicated, but I was thinking of using same work flow.
