Notes

Printed prototypes from my frame projects. Most of these are prototypes for Dirt Jumper V1, Dirt Jumper V2 (built with machined junctions and 3D printed in aluminum) and GST-279: mainly lugs, plus a few junctions and tube sections.

Some parts were printed more than once in different colours: a head tube lug in orange and dark grey, and one junction in white, blue and dark grey. The black sections fit together end to end into one long member, and the grey two-spigot lug takes short rings over its spigots.
