Step 1 — Drawer Setup
Start at the Drawer Setup page.
- Measure your drawer's inner width and depth (in mm).
- If the drawer isn't perfectly square, use the smallest (tightest) measurements.
- Select your printer preset (or "Custom" and enter your bed size).
- Configure grid alignment (left/center/right, top/center/bottom).
- TrayGen automatically computes the Gridfinity footprint and margins.
Step 2 — Fit Test
Go to the Fit Test page.
- Download and print the fit-test shells first.
- TrayGen generates a simple "main + remainder" segment plan for each axis so you can measure a single delta edge-to-edge.
- The ZIP contains two folders: width/ and depth/. Each folder contains:
- main_…_xN.stl: print N copies at +0
- remainder_…_minus5_to_plus5.stl: this is the only segment where you try deltas and choose the best fit
- Each fit-test piece is labeled with a delta like -2, +0, +3.
- Choose the delta that slides in smoothly without forcing, but also doesn't rattle.
- Enter your best-fit deltas (width and depth) in the fit test page.
⚠️ Important: The fit test helps ensure your final plates fit perfectly. Don't skip this step!
Step 3 — Planner
Use the Planner to preview and export baseplates.
- Preview the drawer grid layout and plate tiling.
- See how many plates you'll need to print.
- Click Download plate STLs to export.
- Plates are automatically tiled to fit your printer's bed size.
- Print one STL per print job.
Step 4 — Bins
Design and export bins at the Bins page.
- Drag-select on the grid to create bin footprints.
- Customize heights (Low/Med/Tall/Custom), wall profiles (straight/frontDrop/scoop), and stacking interfaces.
- Create multiple layers for complex layouts.
- Export all bins as a single ZIP file.
Troubleshooting
- Can't access a step? Make sure you've completed the previous steps. The workflow will show a gate message if prerequisites are missing.
- Planner requires drawer setup: Go to Drawer Setup first and configure your drawer dimensions.
- Bins requires drawer setup: The bin grid size is derived from your drawer configuration.
- Want to skip steps? You can click on any step in the stepper to jump ahead, but you'll need to meet the prerequisites first.
- Lost your progress? Your workflow state is saved in your browser. If you cleared site data or switched devices, start again at Drawer Setup.
