Nurbly launches free 6-month drone CAD design competition, final stage requires forking another team's design

The Nurbly platform has launched a free, 6-month drone CAD design competition. Participants design one subsystem each month, in order: airframe, electronics layout, power, control and sensing, and integration, with a final release. Each stage is submitted as STEP files to a public repository. In the final month, participants may fork another team's design and modify one subsystem, with scoring based on the changes. The competition supports any CAD tool that can export STEP, requires no Git knowledge or physical build, and offers $250 per stage and a $1,500 final prize.
