8. Form Follows Production
Easy to source parts and manufactor
• Ideally working towards
• Local manufactoring
• Build to order
• Sandwich construction
• All parts cut on a 3-axis CNC
• Sourced parts are readable available
• Build it in your Makerspace or FabLab
Sandwich construction from
individual layers of MDF.
