Little Rocket LR Fold Foldable Blaster

The LR Fold is a foldable, 3D-printed, single-shot, spring-powered blaster in Tarik’s Little Rocket family platform! Featuring a slim oval plunger tube using a semi-flexible polycarbonate material, this blaster delivers surprising performance in a compact, comfortable package. With the same twist-lock breech as other cousins, this blaster can be “hot-swapped” to fire many different ammo types with corresponding Little Rocket Barrels. Additionally, its compact size and stowable nature allow it to be deployed at a moment’s notice or used as a satisfying fidget device.

This first-ever public 3D fileset for the LR Fold includes everything you need to print the 3D parts and assemble this blaster yourself from our Hardware Kit. If you would like us to print the 3D parts for you, check out our 3D Parts + Hardware Kit!
