My Maker Faire Talk on how to take a MakerBot 3D-printed PLA rocket to Mach 1.8

Jumping to that part of my Maker Faire talk, which I recently discovered online.

Here are the 3D-print files, free on Thingaverse, for 38mm and 29mm minimum-diameter airframes. Total rocket cost is under $10, and total assembly time is about 10 minutes (after an overnight 3D print). A sample Aerotech single-use 29mm H and 38mm J motor are on the table.

Here is a video of a supersonic launch with the same 38mm airframe. The J270 takes this puppy from 0 to 1,363 MPH (Mach 1.8) in 2.6 seconds, pulling 74g’s! According to RockSim, it topped out at 9,454 ft.

A recent launch in Santa Barbara: We made seven of the 29mm ones at XPRS for big rocket experts and their kids First flight of the Falcon Heavy at NASA, with our 3D-printed fairing: Note: launch rods are not rigid enough for the I and J motors; please use the rail guides for 1" launch rails that are integrated into the print. If not…. Fincans Another launch by the seaJ270W in 6 oz. rocket, at Snow RanchFlying again at October Skies
