I just signed up as a fabricator for the Helpful Engineering (@helpfuleng on twitter or www.helpfulengineering.org) project with my Glowforge and Creality CR10 3D Printer. It was quick and easy, and I heard about it from my friend who is lasercutting for them for a hospital in Seattle already. It seems like if you have a bunch of material lying around that would be particularly useful. Here’s the starter doc: https://docs.google.com/document/d/1cM87eJdXhP_8e9gJJZ_SnZXdo_huWsBmMzcqYWbhEOg/preview#
If you are like me and want to look at everything before committing the starter doc has a slack invite and lots of information to check out. I found that soothing.
