Reaches 3,439 m and lands 29.3 m from the pad after 202.8 s. The run marks liftoff at 0.0014 s, 0 m up, then rail exit at 0.173 s, 2.4 m up, then burnout at 2.65 s, 647 m up, then apogee at 23.5 s, 3,439 m up, then drogue deploy at 23.5 s, 3,439 m up, then main deploy at 178 s, 150 m up, then landing at 203 s, 0 m up.

What a run looks like

“Will this printed PLA shelf bracket hold its share of an 8 kg shelf?”

The bracket fails at 52.3 MPa and holds at 9.82 MPa with a gusset.
