We've got a contest on Pinshape for makers! If you print stuff, then entering is simple. You can win FREE MadeSolid filament! There's two winners every week, with winners chosen on Monday.
All you have to do is:
1) Download a Pinshape design (you can upload your own design as well, then print that)
2) Print it out (remember your slicer settings)
3) Upload the print, filling in the slicer settings and comments
This contest is a great way for us to give out a relevant prize for people who already have a 3D printer, and for the community to learn from one another. Hope you guys enter!
