Clip-A-Cap
Modular Hat Clip
Embedded Files
Clip-A-Cap is a comprehensive modular mounting platform engineered to transform almost any variety of headwear into a high utility, hands-free tool station through a specialized "Claw & Ball" friction fit system. This rapidly expanding ecosystem empowers users to instantly swap, rotate, and pivot a diverse range of task-specific attachments. From high-output flashlights and magnetic hardware docks to specialized golf tee holders, this system ensures your essential gear remains perfectly positioned and within reach. Additionally, Clip-A-Cap serves as a powerful assistive device by providing hands-free utility for those with mobility limitations, allowing users to keep tools and visual aids accessible for any professional project or personal adventure.
Project Overview
Project Overview
🧢 Clip-A-Cap is a modular mounting platform designed to transform standard headwear into a versatile, hands-free tool station. Whether for professional trades, outdoor exploration, or accessibility needs, this system moves essential tools from your pockets to your line of sight.
Instead of carrying bulky specialized gear, I developed a universal interface that works with baseball caps, beanies, and straw hats. The goal was to create a lightweight ecosystem that preserves the comfort of your favorite headwear while adding the utility of a professional workstation.
Design Focus
Design Focus
The project is built around a specialized mechanical interface to ensure tools stay exactly where you place them:
🔄 The Claw & Ball System: A friction-fit pivot that allows for 360° rotation and precise angling. This ensures that lights, mirrors, or lenses are perfectly aligned with your specific task.
🛡️ Universal Hat Interface: A non-destructive clip designed to provide high clamping force without damaging the fabric or brim of your headwear.
⚙️ Material Synergy: By pairing rigid components with flexible mounts, the system achieves a secure "click-in" feel that remains easy to adjust on the fly.
The Assembly System
The Assembly System
To achieve the perfect balance of durability and grip, the system utilizes a two-part material strategy:
The Base Clip (PETG): The rigid foundation. Printed in PETG for high strength and heat resistance, ensuring the clip maintains its tension over long-term use.
The Accessory Mounts (TPU 95A): The flexible interface. Using TPU for the ball-joint and tool-holders provides a "rubbery" grip that prevents slipping and reduces wear on the base.
The Modular Attachments: A growing library of tools including the Magnetic Dock, 4-Slot Golf Tee Holder, Flashlight Mount, and Rear-View Mirror and more.

✨ The "Claw" Geometry was the turning point for this design. By engineering a specific tension curve into the PETG clip, I was able to create a mount that stays rock-solid during movement but can be easily removed or swapped. This turned a simple hat clip into a reliable platform for everything from heavy magnets to precision magnifying lenses.
Reflection & Tools

🔍 Key Lesson: Modular design is about tolerance management. Moving to a TPU-on-PETG friction fit allowed for a "silent" and smooth adjustment experience that feels like a professional consumer product rather than a basic 3D print.
