DroneSkeleton

A modular S500 quadcopter (X-frame) airframe modeled in OpenSCAD, with every structural part shipped as a ready-to-print polyhedron and a single assembly file that combines them all.

Features

• Complete S500 X-frame — 4 arms, 4 landing legs, top/bottom center plates, battery tray, side rails and vibration dampers.
• Pre-positioned parts — each *.scad part is an exported polyhedron already placed at its final location (centered in X/Y, correct Z height), so the assembly is a plain union with no manual transforms.
• Symmetry-aware assembly — arm.scad and leg.scad are 4-fold symmetric (one file = all 4 arms / legs); dampers are replicated automatically.
• Parametric mount offsets — rail spacing and battery centering are exposed as variables in drone.scad.
• Optional propeller guard — bolted under each arm tip, auto-generated from an STL and tunable (raised fence or flat profile).

Installation

Build and run the project locally:

git clone https://github.com/colgecen/DroneSkeleton.git
cd DroneSkeleton

No additional dependencies or build step are required — the part files are self-contained geometry. Requires OpenSCAD ≥ 2021.01 and Git.

Usage

Open the full assembly:

openscad drone.scad

Render/export a single part, e.g. one arm:

openscad arm.scad

Export the complete airframe to STL:

openscad --export-format=asciistl -o build/drone.stl drone.scad

The propeller guard is enabled via the variables near the bottom of drone.scad — set guard_wall = 40 to raise the outer fence, or 0 for the flat frame.

Configuration lives in rail_offset and battery_center at the top of drone.scad.
