Scan a tool. Print its place on the wall.

Slotwise scans the tool in your hand with your iPhone's LiDAR camera, then designs a holder that fits it and hangs it on your IKEA SKÅDIS pegboard. It works out how many clips the weight needs, so you just print it and clip it on.

What it does

From the tool in your hand to a holder on the wall.

No CAD, no measuring with calipers, no guessing whether two clips will take the weight.

Scan it with your iPhone

Walk around the tool and Apple's Object Capture builds a 3D model on the phone. Slotwise measures it in millimetres, ready to design around.

A holder made for that tool

It suggests a peg through a closed handle, a side-on holster for drills, or a cradle on shaped arms, and you can switch. Trays get a pocket molded to the scan.

Clips counted for you

Enter the weight and Slotwise adds clips, and grows the plate, until each one carries its share three times over. Pull-test your own clips and enter what they held.

Bins, racks, hooks and cups too

Not everything needs a scan. Make a bin from inside sizes, a rack for wrenches, screwdrivers or pliers, a pair of hooks, or a holder for your coffee mug.

Lay out the board, then see it in AR

Slotwise suggests where everything goes, heaviest near the fixings, and snaps each holder into real slots. Preview the board in 3D or on your actual wall.

Boards that sync and share

Boards, holders and scans sync over iCloud, and one search finds any of them. Share a board with someone so you can both work on it.

The holders

One family, from wrench racks to your coffee mug.

Every holder shares the same shape language: the plate stops flush with the holder, arms are thickest where they meet it, and a smooth fillet joins the two. These are the real parts Slotwise exports.

A wrench rack with a closed back row and an open front row of slots
Rack

WrenchesNew

Two rows: closed slots at the back, open ones at the front, so more wrenches fit in the same width.

A screwdriver rack with a row of holes in a shelf
Rack

Screwdrivers

A shelf of holes with a lead-in, sized to your shafts and spaced for the handles.

A pliers rack with open slots behind a front lip
Rack

PliersNew

Open slots behind a low lip, so pliers can't slide off the front.

A round cup holder on a pegboard plate
Cup

Mugs and cupsNew

Round or oval, sized to your cup, with an optional slot for a mug handle.

A pair of hooks with sloped undersides and lips
Hook

Hooks

One or a pair, shaped like the rack fingers, with a 45° lip at the tip.

A side-on drill holster with two shaped prongs
From a scan

Drill holster

Two prongs shaped to the drill's body, so it drops in nose first.

A peg shaped to the inside of a saw handle
From a scan

Handle peg

A peg molded to the inside of a closed handle, like a recip saw's.

A wide plate with two cradle arms for a multi-tool
From a scan

Cradle

Two arms spaced and shaped to the tool, for everything without a handle to hang from.

Plates flush with the holder Rounded top corners 2.5 mm fillet into the plate Arms thickest at the plate

Surface patterns

Give a board its own finish.

Pick a pattern for a board and every holder on it gets it: on the plate around the holder and the outside walls of bins, trays and cups. Insides and clip pockets stay smooth.

Patterns stand 0.6 mm proud with 45° sides, so they print cleanly with no supports. Smooth is the default.

Made to print

Every holder prints without supports.

Holders print lying on their back, so the rules that keep a print clean are built into the shapes. You get a part that comes off the plate ready to hang.

Bins, trays and cups print standing up instead. Share a 3MF that opens in Bambu Studio ready to slice, or a plain STL for any other slicer.

LIP Every lip rises at 45°So the tool can't slide off, and the overhang prints cleanly

How it works

Three steps between a messy bench and a tidy wall.

Everything happens on your iPhone. No account, and nothing is uploaded to us.

01

Scan

Set the tool on a plain, matte surface and walk around it. Turn it over and scan again to catch the underside.

02

Design

Pick the holder style, enter the weight, and check the preview with the tool sitting in it. Add it to a board when you're happy.

03

Print and hang

Send the 3MF or STL to your printer, with the clips alongside. Push it into the slots, twist the clips, and hang the tool up.

A place for every tool.
