This "log entry" describes the deliberate design choices I will (try) to adhere to while I expand on this project.

Practical Engineering Choices

• Consistent Spacing from the Center of Mounting Points
  • Vertical distance between mounting holes is 25mm
  • Horizontal distance between mounting holes is 25mm or 50m
  • Horizontal distance between mounting holes and the 'side' of a module SHOULD be divisible by 5
    • The goal is to facilitate accessories and modules to connect across multiple modules
• Minimize Support Material
• Parts will be designed to minimize the need for support material
• M3 Hex Machine Screws as standard connectors
  • Various lengths and head styles may be used
  • Visible Screw heads are part of the aesthetic design
• M3 Heat-Set Inserts as standard
• 4mm depth as standard

Artistic Style Choices

• Screw Heads will be visible, and are considered part of the artistic design
• Hexagonal Access Ports and "Speed Holes"
  • Where necessary to include holes and slots, a hexagon should be used
    • A flat surface of the hexagon should be parallel to the bottom  of the component
    • The sides of a hexagon can be arbitrarily stretched to meet the practical engineering need of a hole or slot

Practical Concessions

These are some practical choices I've made that may be sub-optimal, but should be acknowledged as tested and considered.

• Flat sides for Modular Interfaces
  • The sides of a part that are compatible with other modular components should be parallel or perpendicular to the normal.
