Parker Rupe

I'm a high schooler in Boise who designs 3D printers, composite winders, and rockets from scratch, and open-sources all of it.

Projects

Everything here is open source. Each project links to its GitHub repo.

  • Quantumania

    3D printer · High speed

    A quantum delta built for speed, with under 120 g of moving mass.

    • RepRapFirmware
    • Hack Club Highway
    • AWD
    DetailsLess about Quantumania

    Carbon fiber arms and custom composite parts keep the moving assembly that light. It runs a direct-drive BoomBox extruder, AWD motion, MGN12C rails, and three 124 CFM fans.

    Sponsored by Polymaker, Siraya Tech, Fysetc, and Hack Club.

  • CAD render of the RFP Toolhead

    RFP Toolhead

    3D printer · Toolhead

    A toolhead whose cooling duct and heatsink are one piece of SLM-printed aluminum.

    • SLM aluminum
    • CFD-informed
    • MIT license
    DetailsLess about RFP Toolhead

    The part is shaped with airflow in mind. It uses an Orbiter 1.5 extruder and a BTT Eddy Duo Z probe, and I designed it in under 48 hours for Hack Club Rework.

  • CAD render of the ChubY Axis

    ChubY Axis

    3D printer · Hardware mod

    A wildly overbuilt Y-axis for the Ender 3. The chunkiness is the point.

    • 4040 frame
    • Dual MGN12H
    • AWD
    DetailsLess about ChubY Axis

    A 4040 base, 3090 extrusion for the Y, dual MGN12H rails, AWD, and a lot of bracing. Built in about 12 hours for Hack Club Rework.

  • CAD render of the Charlotte CNC Winder

    Charlotte CNC Winder

    Composites · Filament winder

    A CNC filament winder for carbon fiber rocket tubes, with the largest working area of any open-source winder.

    • 60″ × 10″
    • Marlin
    • Hack Club Blueprint
    DetailsLess about Charlotte CNC Winder

    It winds carbon fiber, fiberglass, and basalt on three axes, making tubes up to 60″ long and 10″ across for rocket bodies and motor casings. The axes run on Omegadrive, a belt drive I designed for it.

  • Photo of BECCA held up in one hand

    BECCA

    Rocketry · L1 certification

    My 5-foot L1 certification rocket, with dual-deploy recovery and a GPS tracker I built.

    • 5 ft · 3″ dia
    • Mach 0.8
    • Custom GPS avionics
    DetailsLess about BECCA

    The name stands for Big Engine Certification Completion Attempt. It flies on an Aerotech I500 and is aiming for Mach 0.8 and about a mile up. The tracker pairs a Particle Boron with an Adafruit Ultimate GPS so I can find it after landing.

  • CAD render of the Spaceshot Camera module

    Spaceshot Camera

    Rocketry · Flight electronics

    A camera module built to survive Mach 6+ and keep working past the Kármán line.

    • Mach 6+
    • 100 km rated
    • LoRaWAN PCB
    DetailsLess about Spaceshot Camera

    It’s for a 3″ rocket meant to reach 100 km. An off-the-shelf camera pairs with my own LoRaWAN control board, inside machined mounts and shrouding.

  • CAD render of the To The Moon Together rocket

    To The Moon Together

    Rocketry · Sounding rocket

    A 6-foot N-class sounding rocket aiming for Mach 3 and 19 km, carrying three experiments.

    • Mach 3 · 19 km
    • N-class motor
    • 4 custom PCBs
    DetailsLess about To The Moon Together

    The motor casing is the airframe, with no body tube around it. The experiments are a Geiger counter for cosmic rays, an atmospheric charge sensor, and a test of whether airframe resonance can measure air density.

    Four custom PCBs on a CAN-FD bus, plus a RunCam to film the flight. Launch is on hold for now.

About

I design 3D printers from scratch. Next up: printing parts for space.

I'm a high school student in Boise, and I'm also working on an associate's degree in applied math at Boise State. Most of my time goes into mechanical engineering, especially additive manufacturing.

So far that's meant hybrid delta printers, a composite fiber winder, and high-power rockets. I put everything on GitHub so anyone can learn from it or build on it.

SUNLU Filament sponsors me and has supplied the filament for several of these builds. I've also gotten grants from Hack Club's Blueprint and Highway programs, and sponsorships from Polymaker, Fysetc, and Siraya Tech.

Long term, I want to bring 3D printing into aerospace: winding my own motor casings, printing flight hardware, and eventually getting something to space.
