Core Understanding: System Architecture

These systems form an ecosystem rather than competing alternatives:

Dimensional Relationships:

• Gridfinity: 42mm base unit (horizontal surfaces)
• OpenGrid: 28mm base unit (vertical surfaces)
• Mathematical alignment: 3 × OpenGrid (84mm) = 2 × Gridfinity (84mm)
• Neogrid: Uses multiples of 42mm for Gridfinity compatibility
• French Cleat: Dimension-agnostic (works with any system via adapters)
• Underware: Parametric (sized to cable bundles, snaps into OpenGrid)
• Deskware: Uses 84mm increments (aligns with both Gridfinity and OpenGrid)

Critical insight Claude might miss: These systems are designed to work together in a unified home organization strategy. Users shouldn't choose "one system" - they should combine systems based on spatial context.

Decision Framework: Which System When?

By Mounting Surface (Official Specification)

Surface Type	System(s)	Why
Desktop/shelf	Gridfinity	Magnetic or friction-fit baseplates, easy reconfiguration
Desktop (elevated)	Deskware	Modular risers with Gridfinity/OpenGrid integration
Drawer (small items)	Gridfinity	Bins organize loose parts, paperclips, screws, USB drives
Drawer (large items)	Neogrid	Hybrid approach uses cheap divider material with 3D-printed connectors
Wall (light items)	OpenGrid	28mm grid with front-access snaps, living-room compatible
Wall (heavy items)	French Cleat	45° gravity lock, 100kg+ capacity when mounted to studs
Under desk/wall cables	Underware	Click-and-slide channels, OpenGrid-native integration

By Item Characteristics (Best Practices)

Use Gridfinity when:

• Items fit in 42mm × 42mm × 7mm multiples
• Items need frequent reorganization
• Desktop or drawer placement
• Want magnetic attachment option
• Examples: drill bits, resistors, pens, USB cables, craft supplies

Use OpenGrid when:

• Need wall-mounted access to small items
• Want "living room compatible" aesthetics
• Items under ~5kg per mount point
• Cable routing with Underware integration
• Examples: scissors, tape dispensers, phone holders, printer tools

Use Neogrid when:

• Drawer items too large for Gridfinity
• Want cost-effective large dividers (not fully 3D-printed)
• Organizing clothing, kitchen utensils, workshop tools
• Need reconfigurable drawer layouts
• Examples: t-shirts, spatulas, hand tools, fabric storage

Use French Cleat when:

• Wall mounting items over 10kg
• Need industrial-strength attachment
• Want maximum reconfigurability (lift-and-move)
• Mounting shelves, cabinets, power tools, panels
• Examples: drill charging stations, shelving units, Frenchfinity tool walls

Use Underware when:

• Managing cable bundles under desks
• Need parametric sizing (custom width/height/length)
• Want OpenGrid integration
• Examples: power cables, USB hubs, cable routing, LED channels

Use Deskware when:

• Need elevated desk platforms (monitor risers, keyboard trays)
• Want to combine horizontal surface with grid organization
• Need curved desk sections (corner desks)
• Integrating Gridfinity or OpenGrid into desk surface
• Examples: monitor risers, keyboard platforms, corner desk organizers

By Combination Strategy (Best Practices)

Common combinations that work well:

1. Home office:

   • OpenGrid on wall (scissors, tape, phone)
   • Underware under desk (cable management)
   • Gridfinity on desktop (small accessories)

2. Workshop wall:

   • French Cleat for heavy tools (drill station, shelves)
   • Frenchfinity holders for hand tools (wrenches, pliers)
   • Gridfinity adapter on cleat for small parts bins

3. Bedroom drawer:

   • Neogrid dividers for clothing sections
   • Gridfinity bins within sections for accessories (watches, jewelry)

4. Kitchen drawer:

   • Neogrid for utensil dividers
   • Mixed with Gridfinity for spice packets or bag clips

5. Elevated desk setup:

   • Deskware risers for monitor elevation
   • Gridfinity recesses in top plate for desktop bins
   • Underware under riser for cable management
   • OpenGrid on wall behind desk for tools/supplies

Common Pitfalls

Pitfall #1: Choosing Systems in Isolation

Problem: User asks "Should I use Gridfinity or OpenGrid?" without context

Why it fails: These systems serve different mounting surfaces - Gridfinity is horizontal, OpenGrid is vertical

Better approach:

Question: "What are you organizing and where will it be mounted?"
- Desktop → Gridfinity
- Wall → OpenGrid or French Cleat (based on weight)
- Drawer (small items) → Gridfinity
- Drawer (large items) → Neogrid
- Cables → Underware

Pitfall #2: Over-Printing with Neogrid

Problem: User wants to 3D-print large drawer dividers entirely in plastic

Why it fails: Neogrid's value is using store-bought materials (MDF, plywood) with 3D-printed connectors

Better approach: Print only the X/T/L/I junction connectors (~50g each), cut dividers from 8.5mm utility board ($5 for 10+ dividers)

Pitfall #3: Underestimating French Cleat Strength Requirements

Problem: User wants to use 3D-printed French cleats for heavy items (power tools, cabinets)

Why it fails: Load capacity of plastic cleats is ~5-10kg; wood cleats handle 50-100kg

Better approach:

• Items under 5kg: 3D-printed PETG cleats OK
• Items 5-20kg: Plywood cleats (18mm / ¾")
• Items over 20kg: Hardwood cleats, screwed into studs every 40cm

Pitfall #4: Ignoring Mathematical Grid Alignment

Problem: User tries combining Gridfinity and OpenGrid without understanding 84mm relationship

Why it fails: Accessories won't align properly unless using 3:2 ratio

Better approach: 3 OpenGrid units (28mm × 3 = 84mm) = 2 Gridfinity units (42mm × 2 = 84mm). Design combo layouts using 84mm as the common denominator.

Pitfall #5: Treating Underware as Fully Standalone

Problem: User wants Underware without OpenGrid base

Why it fails: While Underware 2.0 supports magnets/adhesive, it's designed for OpenGrid integration (native snap-in)

Better approach: Install OpenGrid boards under desk first, then snap Underware channels directly into grid. Use magnets/adhesive only for curved surfaces (table legs).

Quality Checklist for Recommendations

Before suggesting a system to users, verify:

Context gathered:

• ✓ What items need organizing? (size, weight, frequency of access)
• ✓ Where will system be mounted? (wall, desk, drawer, under desk)
• ✓ Is reconfigurability important? (static vs. frequent changes)
• ✓ Weight of items? (<1kg, 1-5kg, 5-20kg, 20kg+)
• ✓ Aesthetic requirements? (workshop vs. living room visible)

System selection rationale:

• ✓ Mounting surface matches system type (horizontal vs. vertical)
• ✓ Item size appropriate for system grid (42mm vs. 28mm vs. custom)
• ✓ Load capacity sufficient for item weight
• ✓ Considered combinations rather than single-system approach
• ✓ Checked compatibility matrix if mixing systems

Practical guidance:

• ✓ Referenced specific dimensions from official specs
• ✓ Mentioned material requirements (PLA/PETG, plywood thickness, etc.)
• ✓ Highlighted cost-saving approaches (Neogrid hybrid, Underware iterative)
• ✓ Warned about 3D printing limitations (French Cleat load capacity)
• ✓ Suggested test prints before bulk printing

When NOT to Use These Systems

Don't use when:

• User needs temporary/portable organization → Use bins/boxes instead
• Items are irregularly shaped → Custom-design holders (not modular grid)
• Rental property won't allow wall mounting → Desktop-only solutions
• User has no 3D printer access → Pre-made commercial systems
• Weight exceeds safe limits → Industrial shelving/mounting

Alternative approaches:

• Modular commercial systems (IKEA SKÅDIS for walls)
• Traditional drawer organizers (bamboo dividers)
• Custom woodworking (one-off solutions)
• Pegboard walls (non-3D-printed, widely available)
