What’s New

Photo trace gets you close, but sometimes a shadow or a stray reflection throws off a point or two. You can now fix a traced outline directly, right over your photo.

Open Edit outline on any photo-traced cutout to:

• Drag a point to move it
• Click an edge to add a new point
• Double-click, or select and press Delete, to remove a point
• Zoom and pan to work on fine detail
• Simplify to smooth out noisy points automatically
• Undo/redo every change during the session
• Reset back to the original trace at any time

Every change saves instantly as you go — there's nothing to confirm — and correcting an outline never costs a Photo Trace Credit.

To try it, trace a tool from a photo, then choose Edit outline in the cutout inspector.

A cutout bin can take hours to print — a long wait just to find out a tool is a hair too snug. Now you can check the fit first.

Choose Download fit test under Export STL in the bin editor to get a thin 0.6 mm slice through every pocket and thumb slot. It prints in minutes and is cut from the real bin, at a height every pocket shares, so each pocket appears at exactly the size it will print — same clearance, same shape. Drop your tools in, and adjust the outline or clearance before committing to the full print.

Split bins get one slice per piece, zipped together and numbered like the print queue; pieces with no pockets are left out.

The fit test is available for cutout bins with a traced outline. It isn't offered for 3D mesh cutouts, whose shape changes with depth.

When you trace a cutout from a photo, you can now choose how it's detected. AI Detection costs one Photo Trace Credit, as before. Free Detection never costs a credit — and now you can tune how it traces.

Switch Detection Mode to Free Detection and use Trace parameters:

• Smoothing evens out a jagged edge
• Advanced controls cover blur, how small or large a detected region can

be, gap closing, point simplification, and the working resolution

• Light Tool Mode, also under Advanced, skips color detection and traces

by contrast against the paper — worth a try when a grey or silver tool isn't picked up

Your settings are kept when you switch Detection Mode, so you can go back and forth without losing them. If a trace is close but not quite right, finish it off with Edit outline.

A cutout's clearance is the extra room left around your tool so it drops in without binding. Until now that room wasn't spread evenly: the ends of a long tool — a screwdriver, a scraper, a pair of pliers — got the full amount, but its long sides got much less. On hook and C-shaped tools, part of the pocket could even end up tighter than the traced outline.

Clearance is now applied as a true offset: every edge of the outline moves out by exactly the clearance you set, with neatly rounded outside corners. A 0.6 mm clearance now means 0.6 mm everywhere.

Existing cutout bins pick this up automatically the next time you export them. Their pockets may come out slightly roomier along the sides than a print you made before — if you had raised a bin's clearance to make a long tool fit, you can likely bring it back down.

Sorry about the uneven fits. If this bug cost you a reprint, I've added 25 extra Photo Trace Credits to every paid account as a thank-you for your patience.

A bin that doesn't fit any of your printers used to just block export. Now the planner splits it into pieces instead — each one sized to fit a bed, capped so it prints as its own watertight part.

Splitting happens automatically the moment a bin's footprint outgrows every assigned printer, but you can also add a split on purpose from the bin editor's element list, the same way you'd add a divider or a scoop — useful for intentionally modular bins. Cuts snap to 42 mm or 21 mm grid lines, and the editor tints each piece so you can see exactly how a bin will come apart before you print it.

The print queue and export follow the split: each piece becomes its own queue item, independently checked against your printers and named {bin}-piece-N. If a piece is still too big, only that piece blocks — the rest of the bin exports normally. The export README calls out which pieces are neighbours so you know how to reassemble them.

Delete an auto-added split and the planner leaves it removed until the bin's footprint or printers change again; edit one and it becomes a manual split the auto-planner won't touch.

Measuring a drawer with a tape measure in the US? You can now type new drawer dimensions in inches instead of converting to millimeters in your head.

Pick your unit once on the Account page → Measurement units, or flip the mm | in toggle right in the drawer creation form. In inch mode the width, depth, and height fields accept plain fractions as you'd read them off a tape — 13 3/4, 11, 2 1/2 — and the live Gridfinity fit summary keeps showing millimeters so nothing about the grid math changes.

• Works in both the add-drawer dialog and the new-project wizard
• Flipping the toggle re-expresses what you've already typed in the other unit
• Every stored dimension is still millimeters — the unit is only about how you

enter it, so existing drawers and exports are untouched

This is the first step toward imperial support across the app. To try it, open a project and add a drawer, or set your preference on the Account page.

A large baseplate splits into several bed-sized segments, and printing them one after another means coming back to the printer between every piece. Stacked printing stacks that whole set into a single tall model you start once and collect when it's done.

Open a baseplate in the planner and switch on Stacked printing. Choose how many copies of the drawer you need, the layer height to slice at, and a layout:

• One tower — every segment in a single stack. Fewest print jobs.
• Group by shape — one tower per segment shape, so each piece sits on an

identical one and no supports are needed.

The planner checks the stack against the assigned printer's build height — set it on the printer profile — and caps the copies when the tower would be too tall. On export, a stacked baseplate ships its tower STL(s) plus a README with the copy count, layer height, segment separation, and, for a mixed one-tower stack, exactly which segments overhang and where to add supports in your slicer. Switch stacking off and the export goes back to the usual per-segment files.

The stacking controls are visible on every plan; generating the stacked STLs needs a paid license.

This one is still in beta. I've printed several stacked baseplates on an Elegoo Centauri Carbon with good results — if you run into print problems on your own machine, please let me know so I can tune it.

To try it, open a saved project, select a baseplate that spans more than one segment, and turn on Stacked printing in the inspector.

Imported bins can now sit in a vertical stack with bins you designed in GridfinityStudio — and with each other.

Drop an imported bin onto a matching footprint to stack it, or use Stack another bin on top in the inspector. The imported model's base is treated as Gridfinity standard, so it can go on anything it already fits.

If the STL has a stacking lip on top, check Has a working stacking lip on top when you import it. That lets other bins stack on it. You only get one chance to say so — imported bins stay frozen after import.

To try it, import an STL, place it in a drawer, and drag it onto a bin of the same grid size.

Found the perfect Gridfinity bin on MakerWorld, Printables, or somewhere else? Bring the STL into GridfinityStudio and plan around it in your drawer.

Upload a finished Gridfinity bin or holder, and GridfinityStudio will measure its width, depth, and height, suggest a Gridfinity footprint, and let you confirm the details before adding it to your project.

• Works with binary or ASCII .stl files modeled Z-up. I'm also exploring .3mf

support for Gridfinity bins and holders.

• Measures the bin's width, depth, and height
• Suggests the closest Gridfinity footprint and bin height
• Lets you add a name, category, and optional source link so you remember where it

came from

• Adds the imported bin to your library, or directly into the drawer you're editing

Imported bins are placed as-is. They cannot be edited or customized like bins created inside GridfinityStudio. They can now be stacked — see Stack imported STL bins.

To try it, sign in, open a saved project, and choose Import STL from the bin library.

Every drawer now shows an estimated filament weight, spool cost, and print time before you commit to a print. The estimate updates as you add bins, baseplates, and stacks, so you can compare layouts by what they'll actually cost to produce.

• Weight and length are derived analytically from your geometry — no slicer round-trip
• Cost uses your configured spool price, and works even when the geometry service is offline
• The full breakdown is rolled into the Print Queue alongside your export

Open a drawer and check the estimate panel in the planner to see it in action.

When a project spans more than one printer, your export zip now arrives already sorted — one subfolder per assigned printer, with duplicate parts de-duplicated inside each folder. Single-printer projects still export as a flat set of files, so nothing changes if you print on one machine.

Assign printers per item in the Print Queue, then export as usual.

Set up each of your printers once — bed size and margins — and reuse them across projects. The project setup wizard lets you pick which printers a project targets, and the Print Queue assigns each part to a specific machine.

Printer profiles live in your local planner, so they're available whether or not you're signed in.

Bins can now carry more than one label, so a single compartment can be tagged for everything it holds. Labels flow through to your exports, making printed drawers easier to read at a glance.
