This is a fully parametric 3D model which lets you generate your own personalized storage organizer for USB sticks (USB-A / USB-C), SD cards, microSD cards and a tray for miscellaneous objects. You choose how many Units you want, where they go in the grid, and how large the whole block should be.  The generator allows modification of grid size, Unit count, Unit placement, height, corner radius. You literally generate a configuration based on your neeeds. You can build a simple standalone organizer — or enable full Gridfinity compatibility.

Unit specification:

USB-A = 8 slots (4×2)
USB-C = 8 slots (4×2)
SD = 7 slots (1×7)
microSD = 12 slots (2×6)
Tray = empty catch-all space for irregular items

Quick usage tip:
First choose how many Units your model should have (for example 2×3).
Then decide whether you want a normal standalone organizer or a Gridfinity version, and also if you want optional magnet holes.
After that, in the list you assign which Unit type goes in each position.
Example: Row 1 — Unit 3 = USB-A.
Repeat that for every cell in the grid — this is how you control which Unit appears where in your organizer.

NEW UPDATE: Intelligent Horizontal Merging The new version introduces Smart Unit Merging along the X-axis. When you place identical unit types side-by-side in a row, the generator automatically merges them into a single, seamless "Super-Unit". This removes internal walls and utilizes the extra space to add more slots, maximizing storage density while keeping the spacing perfectly consistent across the entire length.

Feedback:
This is my first parametric model — so this release is still experimental. I’d truly appreciate any feedback or suggestions you have. I want to keep improving this quickly, refine tolerances and presets, and make the whole experience smoother based on what real users tell me.
