diy-gridbeam Gridbeam building system

system

• holes: 2, 3, 4, 5, 6, 8, …
  
• wood and aluminum are interchangeable (but different hole diameters)
  
• count holes to duplicate structures
  
• custom parts with matching grid pattern
  
• tri-joint
  
• tri-joint with double-beam (unoffical?)
  (all axes could be doubled, also note "spare" hole pattern)

  panels have 12mm thickness
• NOT gridbeam (x/y-axes are planar, which is actually desirable)

Modular "Grid Beam" to redesign our context, furniture to bikes

bitbeam – small-sclale Gridbeam

• "Each Bitbeam is an 8mm x 8mm square beam. Holes are 5.0 mm in diameter and 8mm apart from each other – just like LEGO Technic." https://www.thingiverse.com/thing:11747
• screw diameter: 3/16in = 4.7625mm

double tri-joint with zip ties

• https://surfacesreporter.com/articles/133817/guillermo-cameron-mac-leans-furniture-system-easily-adapts-to-different-spatial-needs-liston
• https://design-milk.com/grow-or-shrink-the-liston-furniture-system-in-any-direction/
  • "Using two lengths [!?] of structural wooden slats, it can grow in every direction."
  • seems partially fudged in the pictues
• only grows (easily) in x-direction?
  • with Überblattung
• perhaps z-beams can be stacked, no Überblattung

joint needs \(3s\)

top breaks the pattern, z-beams could be \(s\) longer for true double tri-joint

"Überblattung" of the x-beam: "\(1.5s\)"
