Modular Stim Hand Roller, Multiple options. Ouchie

Keep your hands occupied, your stress levels low, and your focus razor-sharp. The SKS.3D.WS Modular Stim Hand Roller is the ultimate pocket-sized sensory tool, fully re-engineered for total customization. Unlike static fidget toys, this fully modular rolling system allows you to completely customise the height, texture, spin friction, and carry style to match your exact sensory preferences.

Whether you need a compact, low-profile two-gear pocket roller or a full-hand twelve-gear mechanical cylinder, this support-free print-in-place kit puts the build directly in your hands.

THE MODULAR BUILD SYSTEM

1. Stack Heights (Choose Your Length)

Tailor the roller to your exact hand size. The internal core tracks accommodate anywhere from 2 to 12 interlocking gear sections.

• Precision Scalability: Each added gear section increases the total height/length of the roller by exactly 6mm.

2. Three Distinct Section Textures

Mix and match sections along the stack to create a custom tactile landscape for your fingers:

• The Spike Gear: Features sharp, micro-frequency ridges for high-sensitivity tactile input.
• The Ripple Ridge: Deeply grooved industrial blocks for maximum grip and rhythmic rolling.
• The Smooth Tactile: Subtle, low-impact wave geometry for a soothing, low-friction glide.

3. Two Section Spin Styles

• Smooth Free-Glide: Sections rotate completely independently with subtle reduced mechanical resistance.
• Classic Friction: Sections rotate completely independently with subtle mechanical resistance.

4. Three Top Cap Configurations

• Stock (Flush): A clean, flat finish that maximizes pocket comfort and maintains a low profile.
• Lanyard Loop Holes: Features dual passing holes optimised for small loop Ø3 mm holes x 2 
• Keyring Hole: A threaded top section with a keyring hole attached to it. 

PRINT INSTRUCTIONS

• General Layer Height: 0.2
• Walls: 3–4 perimeters. This gives the central core axle and individual gear walls the structural rigidity required for thousands of rotations.
• Supports: 100% print-in-place optimization. Designed to print completely support-free.
