Parametric parts for 3D printing

Parts that fit, made in your browser.

Write a part as a few lines of code, generate Gridfinity bins and whole drawers, or upload a model you already have. Every design runs in your browser, downloads as STL or 3MF, and is a short link anyone can open and adjust.

PPSCAD
// Knob: grip ridges and a D-shaft bore, printed top face down
param knob_d: float = 30 [12:60:1] "Knob diameter (mm)"
param height: float = 16 [8:30:1] "Height (mm)"
param shaft_d: float = 6 [3:10:0.1] "Shaft diameter (mm)"
param flat: float = 1.5 [0:3:0.1] "Depth of the flat (mm)" "0 for a round shaft"
param bore_depth: float = 12 [4:25:0.5] "Bore depth (mm)"
param ridges: int = 18 [0:48:1] "Grip ridges"

23 more lines build the geometry from these numbers.

Drag to orbit, scroll to zoom. Arrow keys orbit, plus and minus zoom, F fits the model.

Parameters

Four ways to make a part

Start from code, from the Gridfinity generator, from a drawer you measured, or from a model you already have. Each ends in an STL or 3MF and a link that carries the sizes.

  • Write it as code

    A few lines of PPSCAD. Every param line becomes a slider, and the model follows as you type.

    Open the editor

  • Generate a Gridfinity bin

    Bins, baseplates, lids and labels to the specification, with every size in the link.

    Open the generator

  • Fit a whole drawer

    Measure the drawer, split the baseplate over your print bed and lay the bins out in it.

    Plan a drawer

  • Upload a model

    STL, OBJ or 3MF with photos and a print profile; every upload is checked before it is listed.

    Upload files

How it works

Everything runs on your machine

The Manifold kernel and a Rust renderer run in your browser, so nothing waits on a server. The server keeps only the designs you save.

  • Built as you watch

    Move a slider and the model is rebuilt in a fraction of a second for most parts.

  • Sizes travel in the link

    A design's address carries its values, so the next person prints the same fit.

  • Yours to print

    Download STL or 3MF, free, and open the code of any design in the editor to make it your own.
