Kit-card Nerf Gun (working model)
The CMR Lab collaborated with Mark Rober (Watch his video) and his team to develop the smallest operational Nerf blaster in the world.
This print is the ¼ -size version, kit-card version measuring roughly 10x6 cm.
It's important to use PLA or nylon filaments so as to get the best mechanical properties out of this model.
NO assembly required (8 bullets are on the build plate)
Update: some users are reporting some dimentional inaccuracy of the darts so i suggest printing the "smaller darts by @toiavalle"
