Is there a specific cut off time on March 21st? You mentioned that the winners will be decided on March 21st so there must be a cut off time in order to give the Ultimaker / 3D Hubs team members enough time to go through all the submissions and decide on the winners.
+1 for NEW DESIGNS. Seems like someone is downvoting people all around and put you into the negatives. I really hope the judges totally neglect the votes. It’s creating a bad aura for the entire community.
