A tactile sensory tool designed for controlled pain stim or deep sensory feedback. The cylindrical body is fully covered in square-pyramid studs for high-intensity tactile input, while the smooth dome cap provides a comfortable pushing or rolling surface.

Created in OpenSCAD and fully parametric — adjust stud height, spacing, cylinder size, and dome profile to suit your preference. Ideal for fidgeting, sensory regulation, or focused tactile stimulation.

Features: • Square pyramid studs arranged in maximum-density packing around the cylinder. • Smooth dome cap for safe pressure application. • Parametric design — easily customize dimensions and spacing. • Printable in rigid materials for sharper feedback or flexible filaments for gentler stimulation.

Print Notes: • No supports required for the main model. • Increase wall count for durability under pressure. • TPU/TPE recommended for softer feedback; PLA/PETG for sharper sensation.
