rear ejection couplers for boost glider pop-pods and other model rockets

thingiverse

Rear ejection couplers for boost-glider pop-pods and other model rockets. They look like Y-couplers on the outside, but are U-vented on the inside. In handy-dandy BT-5, BT-20, and BT-50 sizes. I recommend printing these on their sides with a raft and supports only to the bed. While it looks more intuitive to print them standing on end, that way breaks too easy because of weaknesses in layer lamination.
