I want a building brick that clicks together with my kid's existing bricks: a 2x4 one and a 2x2 one, and they have to hold on to each other and on to the real ones.

Material
PLA

Two bricks that click into an existing system: the studs and the tubes underneath are held to the system's clutch tolerance.
