For Duality LED Track & HexGrid

Plan the whole wall before you print a single part.

Snap together straights, corners, Tangent curves and Vitality peaks to scale, watch the lighting run through it, and walk away with the exact list of files to print.

Real session, sped up a little. Click a part to add it at the open end. The print list, LED length and power update as you go.

Built around the real parts

Every piece in the palette matches a file in the Duality listings, so what you draw is what you print.

Every track family

Straights from 100 to 400 mm, 45° and 90° corners, Tangent curves at R100, R175 and R225, Tee and Cross junctions, all ten Vitality pieces, 707 corners and the up/down pieces that leave the wall.

HexGrid painter

Paint hexagons onto the honeycomb. Shared edges count once, and connectors are tallied as 2-way or 3-way, for standard or NEST builds.

The exact print list

File names straight from the listings, like E_Tangent_90_R175 and Skin_MatteHex_90_250_LH, with quantities, couplings and the right left- or right-hand skin. Download it as CSV.

Light it up first

Preview solid, gradient, rainbow, chase and breathe effects running along the strip from the controller, the way WLED will drive it.

Strip and power math

Overall size in metres and inches, metres of LED strip, LED count at your density, and peak current at 5 V so you buy the right supply.

Save, share, adjust

Designs save in your browser and as .json files you can reopen or send. Six diffuser skins, PNG pictures, and dimensions you can tune to your printed parts.

Questions

Is this the official Duality app?

No. Trackline is an independent planner. The Duality part files are designed and sold by their creator on Printables, and you need your own copy of them to print anything.

How exact are the dimensions?

Shapes and part names come from the published files and the 1:20 layout stencils. Some measurements, like Vitality angles, are estimated, so you can correct them in the planner.

Where are my designs saved?

In your browser, automatically. To move a design to another device or share it, download it as a .json file and open it there.

Found a problem?

Write to [email protected] with what you were building. A downloaded .json of the design helps a lot.
