Spiky Sensory Container Roller Grip

Spiky Sensory Fidget Roller Grip and Self-Regulating Stimming with Container

Feeling fidgety? Overstimulated? Just need a moment to reset? Want to hide something away?

🌀 Spiky, yet soothing: Each little spike helps delivery tactile satisfaction you didn't know you needed.

🌟 Self-regulate your own levels: Gentle grip when you’re calm, firmer when you’re not. You're in full control.

🖐️ Palm-perfect: Compact, silent, and discreet for on-the-go grounding.

🎁 Makes a perfect gift for sensory seekers, neurodivergent friends, or anyone who needs a little peace in their pocket.

🎄 Especially great for Christmas stockings, care packages, or cozy winter surprises.

‼️ Screw-off cap allows you to easily store little valuables or knick-knacks.

What? Why?

• Sensory regulation: Pain stimming can provide a sense of grounding and focus by stimulating the nervous system.
• Emotional expression: It may serve as a way to cope with overwhelming emotions, such as anxiety or frustration.
• Self-soothing: Pain stimming can provide a sense of comfort and relief, similar to the soothing effect of a warm bath or massage.

Inspired by "Little Ouchies" line of products.

More Info:

• The “Sparse” version has more intense spikes.
• The “Dense” version has regular, less-intense spikes.
• The “Split” design has two halves that open in the middle.
• The “Full” design has a small cap at one end.
• The full height is about 89mm tall (~3.5 inches), and 35.4mm wide (~1.39 inches).
• The inside area is 85mm (~3.35 inches) by 19mm (~0.75 inches). This is big enough to hold something like a tube of ChapStick or rolled-up US dollars.

Notes: 

• Due to the intricacies of the spiked surface and the threads used, a slightly slower print speed is set in the print profile.
• It is recommended to not change any of the settings in the 3MF print profile and to make sure that you have properly calibrated your printer for your particular filament.
• Please do not try to stick anything inside that might get stuck.
• To avoid damaging the threads, please avoid over-tightening the container.
