Role
Soft goods design: research, materials, patterning and sewing.
Problem
Framers’ tools end up on the ground: rigid boxes are heavy and tool belts hold too little.
Result
A trifold roll that folds to 11″ × 8″, holds two power tools, and hangs on studs.

Overview

TNT Tool Roll

On a framing site, workers carry only what they need, and their tools still end up scattered, unprotected, or buried. I wanted a way to carry, reach, and protect essential tools quickly and simply.

The result is a foldable, weather-resistant soft goods system built around a framer’s workflow.

Understanding a framer’s daily habits

Problem statement

My user group: construction framers aged 30 to 50. They move constantly between their truck, the ground, ladders, and studs. Their workflow is fast, physical, and outdoors, all while being exposed to dust, moisture, and uneven terrain.

These insights shaped the product goals: fast access, compact organization, portability, and protection.

Rigid boxes: heavy and slow

  • Often left behind when workers move zones.

Tool belts: not enough

  • Only carry essentials, leaving medium tools unorganized.

Mid-day transitions: messy

  • Tools end up on the ground or in piles, creating clutter and safety issues.

Where current products fall short

Existing products solve part of this, but none I found carry one or two power tools plus key accessories in a compact, foldable format that stays off the floor. That left room for a hybrid soft good: portable and flexible, with just enough structure.

Klein canvas tool bag

Soft pouches and duffels

Flexible, but too unstructured. Doesn’t protect or hold power tools adequately.

Milwaukee PACKOUT rigid system

Rigid systems (e.g., PACKOUT)

Durable, but heavy and mainly stationary. Limits mobility on dynamic jobsites.

Ideation

Focusing on a versatile “tool roll” which folds into the 11″ × 8″ constraints. A trifold design with a fold down to the middle, giving the whole unfolded construction a 16″ × 33″ frame. Incorporating multiple ways to carry the tool case, and multiple ways to hang and attach the product to studs. Looking at different ways to attach tools and secure the tool case in general.

Off the floor

Hanging on studs

Able to fit onto studs after nails are placed for hanging. Keeps tools and accessories off the jobsite floor. The handle integrates with the speaker for a co-employee workspace.

Final design

My final design is a trifold, 33″ × 16″ tool roll that folds into an 11″ × 8″ compact form, holding:

Power toolsTwo full-size power tools (with batteries attached)
PocketsAccessory pockets for bits, blades, clamps, and mid-size tools
StructureFlexible panels + rigid reinforcement
HangingEyelets at 16″ and 24″ for direct stud attachment

Materials for the jobsite

Scholarly research (Backer & Tanenhaus) on textile geometry informed Cordura use. Research (Forteza et al.) on job-site complexity reinforced the need for clutter reduction.

Cordura 1000DHigh abrasion resistance, structural stability, weather protection. Ideal for outer panels and tool sleeves.
Ripstop nylon (≥100D)Reduces weight; increases flexibility in fold zones and interior pockets.
HDPE internal panelsAdds structure for heavy tools without compromising foldability.
Webbed nylon + bartacksEnsures durability at stress points and frequent folding seams.

Prototyping and construction

My first prototype taught me about seam allowance, thickness, and construction order. The final prototype is stronger: it folds smoothly, hangs securely, and holds tools firmly.

Most construction was done by having a main 33″ × 11″ orange ripstop frame, and then layering Cordura 1000D on top of it once all attachments were on the cut pieces. The Cordura 1000D pieces are then attached to the ripstop base and sandwiched around the HDPE to conceal it securely. The final step is to cover all open areas with nylon webbing.

User testing insights

What the first loaded prototype showed.

Weight

Bag is heavy when fully loaded (expected).

Support

Handle and eyelets successfully supported full load.

Security

Straps effectively secure drills and drivers.

Refinement

Middle pockets need improved tightening for smaller tools.

What I learned + future directions

I learned a lot about soft goods construction, from how materials behave to how to plan the stitching. I learned to combine structured and flexible fabrics, add hardware, and mix several materials in one fabric product.

Next steps for refinement

  • Edge binding construction
  • Strapping systems for small tools
  • Weight distribution and handle padding
  • Optional modules for different trades
