SLICC GF H9 W1.0 – Gridfinity Compatible Lidded Cartridge Storage System

SLICC GF H9 W1.0 – Gridfinity Compatible

SLICC is an open, 3D-printed, modular storage standard for anyone who wants spill-proof, color-coded, easily labeled, and transport-safe organization for small parts.

This model provides the Family H9 W1.0 implementation for Gridfinity. It includes the racks cartridges, including sliding-lid and SMD micro-lidded cartridges.

These racks use half-grid pegs compatible with standard Gridfinity baseplates, offering double the mechanical resolution making W1.5 possible.

SLICC: Enhance Your Storage

What is SLICC?

SLICC is an open, 3D-printed, modular storage system enhancement for anyone who demands high-granularity, spill-proof, color-coded, easily labeled, and transport-safe storage for small parts.

SLICC works as a two-part system:

• Cartridges: Modular, lidded, labeled, and color-coded containers.

• Racks: Adapters that let cartridges fit into your preferred storage system.

Note

Cartridges and Racks are system-specific Pick the right SLICC Version for your storage system.

Currently, SLICC integrates with Festool Organizers and Gridfinity, but the concept is adaptable to almost any modular storage solution.

SLICC Principles

Each letter in SLICC reflects a core design goal:

Slotted

• Cartridges interlock with the rack, staying secure - even if neighboring cartridges are removed.

• Rack geometry keeps lids closed for passive security.

Lidded

• All cartridges come with lids.

• Standard cartridges: Sliding lid with integrated stop - no lost lids.

• SMD cartridges: Small, lidded compartments (with hinges) secured by a larger locking lid with snap closures.

Identifiable

• Every cartridge has a dedicated label zone sized for standard labels: 2U: 6mm, 3U: 9mm, 4U: 12mm, etc.

• Easy to scan and organize - find the right part at a glance.

Compact

• Vertical layout with fine-grained slot spacing gives you just the right box size - no wasted space.

• Mix subdivided cartridges (e.g., 12-compartment SMD) and larger ones for bigger parts - all fit the same rack.

• Rack width matches parent system’s grid units - perfect integration, no dead space.

Color-Coded

• Filament channel for snap-in color coding

• Change colors anytime, no need to reprint.

• Or obviously print in multiple colors.

Why SLICC?

I built SLICC because no other system truly met my needs:

• Other options (like Gridfinity) are great, but small parts still spill, and outside containers require massive, time consuming prints, if they fit on the bed at all.

• Off-the-shelf storage lacked the modularity, labeling, and flexibility I needed.

• Festool Organizers (especially the SYS3-SORT/3) are almost perfect - sturdy, transparent, interlockable, and with drawers - It just wasn't SLICC enough ;)
