01 — Workflow

From idea to print bed
in four steps.

No CAD software, no export plugins, no version mismatches.

STEP 01

Pick a base

Choose one of 26 base shapes, start from a ready-made template, or trace your own shape from a photo.

STEP 02

Tune every parameter

Drag sliders for size, walls and corners, and add dividers, lids, drawers and text while the preview updates live.

STEP 03

Check the fit

See it on your printer’s bed, fill a drawer with matching bins, or place it on your desk in AR before you print.

STEP 04

Export & print

Download a slicer-ready STL. Models with a lid, drawer or baseplate come as a zip with one STL per part.

Sous-vide bag rack
MAIN PURPOSE: Hold vacuum bags upright in water bath
Stands vacuum bags upright in five slots so the water circulates round every bag in the bath; the open floor and slotted walls let it flow. Print it in PETG for cooking temperatures.

Stackable Knife Tray – 6 Slots (Customisable Size)
MAIN PURPOSE: Store knives safely in separate slots
A slim, stackable knife tray with six slots that hold kitchen or craft knives upright and apart, so the blades don't knock together and stay easy to grab. As it comes it's 210 × 70 × 33 mm with slots about 7 mm wide. That suits paring, utility and steak knives, chisels, scalpels or hobby blades. Every dimension can be changed in the editor: width, depth, height, wall thickness, and the number and width of slots. That way you can size it for your own drawer and knives. The Raised grip base lets one tray stack firmly on another, so you can build a tidy column in a drawer or on a shelf. It prints as one solid piece with no supports.

Newel Stair
MAIN PURPOSE: Store pens by length in a winding stair of cups
A pen tower that climbs like a spiral staircase round its newel. Four cups wind upward round a tall central post, each a step higher than the last, so short pencils sit low at the front and long brushes stand in the newel, and you reach each height by turning the stair.

Vaze Swirl Bottle
MAIN PURPOSE: Display dried flowers or a single stem
A small bottle vase with a round belly and a narrow neck, wrapped in sharp pleats that twist 45° around it. The pleats are deepest at the belly and thin out towards the neck, so it reads like a classic bottle with a swirl. About 110 mm across the pleats and 100 mm tall.

Prints in one piece with no supports. Change the size, the belly or the neck in the editor to make your own.

03 — Capabilities

Every parameter,
under your control.

Six tools working together, so you never have to open a CAD program.

01

Parametric controls

Set the size, walls, corners, dividers, holes, text and wall patterns with real-time sliders.

Every slider shows its exact value in millimetres, and Undo, Redo and the History tab let you step back at any time.

02

Instant STL export

One click downloads a watertight STL that works with every major slicer and printer.

Parts that print separately, like lids, drawers and Gridfinity baseplates, download together as a zip with one STL per part.

03

Augmented Reality Preview

See your organizer at real size on your desk, drawer or shelf through your phone’s camera before you print it.

Tap “See it on your desk” on Android or iPhone and place it on your desk. On a computer, scan the QR code to open it on your phone. No app or account needed.

04

Playback steps

Every edit is captured as its own step. Scrub through a model's build history, or hit play and watch it unfold.

The History tab records each parameter change individually — jump straight to any past step, or replay the whole sequence from first slider drag to final export.

05

Version history

Every save becomes a version. Roll back to any earlier step or saved version in a click.

Choose which saved version people see when you share a link, and tidy up steps you don’t need.

06

360° tour

Every model gets a one-click auto-orbit tour. Share a link and let anyone spin through it hands-free.

The same orbit that powers the Showcase page's own Tour popup — drop it in an iframe with `&tour=1` on any share link to embed it anywhere.
