I designed some shirts and made them available for everyone Multirotor Pride
If you dont know about teespring, you place an order during a time frame and when it expires, they make the shirts and ship them out to you. Teespring will only make and ship the shirts if there are enough orders within the campaign. Currently, most items are on 7 days (About 5 remaining 6/30) to ensure there are enough orders. I will make sure though, if you were to place an order, that you will get that item.
