[Hardware] FYI returning Stratasys cartridges

Hi Everyone,

Please remember to use all the filament possible in the Stratasys F170. It will allow you to change in the spools in the middle of the job. When a spool runs out, we should put it back in the box and then put them back in the cabinet until we have 3 or more, at which point we can ship them back to Stratasys for recycling.

Thanks, -John
