OpenSCAD¶

The MakerPanel OpenSCAD library is the reference implementation for creating parametric panels, rails, and rack components. It can generate both 2D profiles for laser cutting and 3D solids for printing or CAD interchange.

Recommended editor¶

We recommend using the Robot Developer Extensions URDF editor for VS Code. Its OpenSCAD support provides direct .scad editing, automatic 3D previews, Customizer controls, library-path integration, and STL/SVG export. See OpenSCAD - Robot Developer Extensions for URDF editing for installation and usage details.

Requirements¶

• OpenSCAD
• Git, or a downloaded copy of the MakerPanel repository
• Windows, Linux, or macOS

Installation¶

1. Download or clone the repository:

   git clone https://github.com/Ranch-Hand-Robotics/makerpanel.git

2. Add the repository's makerpanel/ directory to your OpenSCAD library path, or keep your design inside this repository and use a relative include.

3. Confirm the library is available by opening a new file and including the panel API:

   include <makerpanel/panel.scad>

When using VS Code with the URDF Editor extension, this repository already configures makerpanel/ as an OpenSCAD library path in .vscode/settings.json.

Create a panel¶

The primary APIs are:

• makerpanel_2d(width_hp, height_u) — a 2D profile for SVG or DXF export
• makerpanel(width_hp, height_u, thickness) — a 3D printable/extrudable panel

A minimal configurable panel looks like this:

include <makerpanel/panel.scad>

/* [Customization] */
horizontalPitch = 8; // [1:1:64]
verticalUnits = 1;   // [0.125:0.125:5]
panelThickness = 3;  // [1:0.5:6]

/* [Part Selection] */
part = "panel_3d"; // [panel_3d, panel_2d]

if (part == "panel_2d") {
    makerpanel_2d(horizontalPitch, verticalUnits);
} else {
    makerpanel(horizontalPitch, verticalUnits, panelThickness);
}

Open the file in OpenSCAD, adjust the values in the Customizer, and render the selected part.

Export files¶

• Select panel_3d, render with F6, then use File → Export → Export as STL for 3D printing.
• Select panel_2d, render with F6, then export as SVG or DXF for laser cutting or import into another CAD package.

Add controls and cutouts¶

Use difference() to subtract component openings from the standard panel body. Keep component dimensions in named variables so the design remains easy to adapt and verify.

include <makerpanel/panel.scad>

module control_panel() {
    difference() {
        makerpanel(12, 1, 3);
        translate([0, 0, -1])
            cylinder(h=5, d=7, $fn=48);
    }
}

control_panel();

Library modules¶

Browse the repository's examples/ directory for complete designs with Customizer controls and part selectors.

Verify your design¶

Before manufacturing, check the design against the MakerPanel specification, especially:

• HP and U dimensions
• mounting-hole placement
• panel thickness and component depth
• T-slot rail and fastener compatibility
