Ky's kits were a 2/3rd Scale version of the original’s featured in the movie October Sky, exactly 20 years ago (at the time of the kit's release)! The Rocketman's Miss Riley Ky provided some part specifications (his were fiberglass) and a RockSim simulation file (which I can open in OpenRocket ) so I decided this would be a good 3D printing project. Leveraging my recent work on 3D printing nose cones...

For Christmas, my family gave me a Featherweight GPS tracking device in addition to my 3D printer .  This led me to begin exploring ways to 3D print a device to hold the Featherweight GPS device in my rocket.  Featherweight provides STEP files for holder integrated in 38mm nose cone, but not something I knew how to use. After some research I found a Featherweight pod design by Jamie Claye on Printable .  I tried printing them the way the files came, laying on their side multiple times before I learned to reorient the object in Ultimaker Cura before printing them vertically and correcting all the problems.  This is designed to hang on the shock cord Laying out the Featherweight pod parts for slicing in Cura His Featherweight holder is designed to hang on the shock cord and protect the GPS device. Featherweight Tracker Pod design by Jamie Claye Separately, I found some great designs for 4" and 3" body tubes that include bases that screw into the bottom of nose cone wi...
