Vertexprint

Vertexprint Preview

Vertexprint (https://agentelement.net/vertexprint) is a tool for converting meshes into 3D printable assemblies. The tool takes a mesh as input and generates:

  • STL files for vertex holders - printed components that hold rods in place.
  • A table of edge lengths - cut your rods to these lengths, either by hand or with a laser cutter.

The generated assemblies use interference fits: vertex holders have slots that rods slide into. For complex parts, vertex pieces and edges can be labeled. Each slot on each vertex is labeled with the corresponding edge; use these slot numbers to determine which edges go where.

If you use a laser cutter to cut your rods, then vertexprint also generates SVG files to cut rods in batches.

Usage

Vertexprint is available as a webapp here. It renders all your STLs in the browser, and no data leaves the browser.

You may also run it as a bare python script. See installation instructions below.

# Generate a stanford bunny.
uv run python scripts/vertexprint.py \

--offset-type per_half_edge \ # Vertex pieces can have nonuniform offsets
--radius 750 \ # Rescale object such that the vertex furthest from the origin has this distance from the origin
--rod-inset 6 \ # Rods are inset by this distance
--isotropize \ # Make faces as equilateral as possible (avoids small angles) -- good if your vertex pieces come out wonky
--label-vertices \ # Add labels to vertex pieces
--generate-outputs

David McCooey's website has a number of polyhedra definitions in a uniform text format. The data/ directory includes all Platonic, Archimedian, Catalan, and Kepler-Poinsot solids in this text format. I have written a simple utility to convert from this text format to a .obj format suitable for the main vertexprint program.

Installation & Development

This project uses Nix for environment management and uv for Python dependencies. You only need to have Nix installed to develop for this project. Nix manages everything else for you.

# Enter the development shell
nix develop
# Install dependencies with uv
uv sync
# Run tests
uv run pytest

If you don't want to use nix and uv, then you must install openscad from your system package manager. After that, install the dependencies listed out in pyproject.toml and run the vertexprint script normally.

David McCooey's website has a number of
polyhedra definitions in a uniform text format. The data/ directory includes
all Platonic, Archimedian, Catalan, and Kepler-Poinsot solids in this text
format. I have written a simple utility to convert from this text format to a
.obj format suitable for the main vertexprint program.

Installation & Development
This project uses Nix for environment management and uv for Python
dependencies. You only need to have Nix installed to develop for this project.
Nix manages everything else for you.
# Enter the development shell
nix develop
# Install dependencies with uv
uv sync
# Run tests
uv run pytest
If you don't want to use nix and uv, then you must install
openscad from your system package manager. After that,
install the dependencies listed out in pyproject.toml and run the vertexprint
script normally.

Vertexprint
Vertexprint Preview
Vertexprint (https://agentelement.net/vertexprint) is a tool for converting
meshes into 3D printable assemblies. The tool takes a mesh as input and
generates:
  • STL files for vertex holders - printed components that hold rods in
place.
  • A table of edge lengths - cut your rods to these lengths, either by hand
or with a laser cutter.
The generated assemblies use interference fits: vertex holders have slots that
rods slide into. For complex parts, vertex pieces and edges can be labeled.
Each slot on each vertex is labeled with the corresponding edge; use these slot
numbers to determine which edges go where.
If you use a laser cutter to cut your rods, then vertexprint also generates SVG
files to cut rods in batches.
Usage
Vertexprint is available as a webapp here.
It renders all your STLs in the browser, and no data leaves the browser.
You may also run it as a bare python script. See installation instructions below.
