Basics

A lightweight (200 kg) 3 occupant vehicle design that can be mostly DIY constructed.
Dimensions 1.5 x 3.1 x 1.1 metres for a front surface area of approx 1.5 sq. metres
Geodesic Frame skeleton is bamboo and PVC pipes connected together with 3D-printed software-generated "Nodes", which are then entirely encased in Expoxy Resin and Fibreglass, Kevlar, Hemp, Flax or other high-strength cloth layers.
Double wishbone suspension is expected to be fitted at the front, whilst the rear may be swing-arm, Double-wishbone or Macpherson. This revision uses swing-arms at the rear.
Body panels are twin layers of Fire-resistant Non-woven Polyester with a hot-glued 4 layer latticework "Hobbycraft" 9x1mm bamboo frame inside (9x1mm is easily bendable) to create compound curves. Label-gun "barbs" pin the two polyester sheets at a regular 10mm spacing, and Soudal Fire-resistant Expandong foam injected into the gap.

Frame Concept

Blue pipes are 1m measure sticks. Note that the body takes whatever form we would like.

Inner frame using 3D-printed fibre-reinforced "nodes" connecting continuous-fibre-reinforced pipes on a Fibre_Reinforced_Pipe_3D_Printer or getting carbon-fibre, hemp-reinforced tubes (or even Bamboo), based on the Divergent 3D "Blade" car manufacturing concept https://www.youtube.com/watch?v=vPv7PwS50OE
