The Do-it-Ourselves PLASTIC-x2
The PLASTIC-x2 is my 5th prototype. Rather than having a trike wheel, this design uses (2) 4" front caster wheels. This design is more suitable for smooth terrain. Note. The second version uses a 5" caster which improves its ability to handle rougher surfaces.
The PLASTIC-x2 is very similar to the 2x3-x2. It uses PVC boards purchased from Home Depot. I think that regular (wood) plywood would also work. The side holes are for design fun.
