About this model

The Compliant Mechanisms and Robotics Lab has worked with Mark Rober and his team to create the world's smallest functional Nerf blaster. Watch his video here! EDIT 10/16/2023: The ¼-scale files have been updated to a version that latches much better. The smallest functional blaster is manufactured with carbon nanotubes and is small enough for an ant to use, but we have created four 3D printable scaled versions just for you! We also made a version that does not look like a gun for teachers and others. A fun disk launcher was the result, and the files can be found at Read our related technical paper, coauthored with Mark Rober, published in PLOS One, and a related article in Nature Communications.
