THE STORY:

I designed this model for an exhibit at Open Sauce 2023 San Francisco. It's a very cool event that I'm excited for and I wanted to provide an opportunity for people to take home something to remind them of it after.  

FEATURES:

  • 1 rubber band → bowstring & trigger tension design
  • print-in-place trigger mechanism
  • snap-fit parts
  • functional @ .3mm layer print quality (for faster mass production)
  • ergonomic thumb rest

PRINTED PARTS:

  • QT BOW Body (mini or standard)
  • QT BOW Limb (mini or standard)
  • QT BOW Barrel Mod

NON-PRINTED PARTS:

  • flat rubber band (ideally 3½" X ⅛" or 88㎜ X 3㎜)
  • standard q-tip (or non-standard…?)
