3D Prints:

đź’ˇ

All main components of the rocket (omitting body-tubes) were designed in CAD with an emphasis on balancing aerodynamic performance, structural integrity, and manufacturability through prototyping (V1 → V3).

Many prints that were designed for the rocket initially went through issues that affected the rocket such as incorrect CAD settings or physical printer issues. Often times, many prints go through several iterations of the design, such as the rocket fin. This evolved from:

V1 Fin
V2 Fin

V3 Fin

Notice a difference between different versions? Didn’t think so. Although the minor changes between different iterations may seem negligible, the change that they impart on the overall center of gravity and center of pressure can greatly affect rocket flight.

  • V1 mainly focused on overall flight characteristics and prototyping (printed using PLA)
  • V2 prioritized aerodynamic efficiency through a modified shape and improved leading edges (printed using ABS)
  • V3 improved on design changes from rocket body shrinking from 57” to 45”, therefore having to compensate by having larger control surfaces for balanced CG and CP (printed with ABS)

Parts:

  • Nose

    Designed to reduce aerodynamic drag while also serving as a crumple-zone in the event that the rocket were to crash, protecting the critical payload and rocket body. Early version prioritized structural integrity (V1, V2), while later iterations traded structural integrity for survivability, since nose-cones are easier to print than an entire rocket.

    The use of screw couplers allowed for the secure attachment of the nose cone to payload bay:

  • Couplers
  • Fins
  • Engine Tubes
  • Spacers
  • Screws
  • Payload

4/6: Print failed due to lack of adhesion to print bed, will add isopropyl alcohol to bed to clean and adjust slicer settings to ensure maximum adhesion

4/12: Resolved issue through manually re-calibrating bed through gear-tuning and paper to correctly calibrate z-offset and purchasing new filament
