ROCKMine is a marble run hidden inside an organic rock formation — designed to sit on your desk and make people pick it up every time.

Drop a standard 16mm marble into the mine shaft at the peak. It disappears. Seconds later it emerges from the tunnel portal on the face of the rock, and launches into the air! You'll do it again immediately.

Engineered with the same design philosophy as every S33D Studio piece. The tunnel path is sized precisely for smooth marble travel and was intentionally designed to not need any supports.

This is part of the S33D Studio catalog — a growing collection of functional objects designed around natural forms and engineering precision.
