More parametric stuff – another design

I decided to create another grid and try some  alternate ‘maze’ waveguide ideas to see if I can optimise the path…….I think I have!

The grid is made of formulas – waveguide height and wall width and entirely construction lines.

To create the purple ‘walls’ it’s easy enough to drag the mouse, highlighting the required walls and press ‘X’ twice to toggle construction lines on / off

Some experimenting with sizes eventually gives a waveguide length of 770mm near enough… I can fairly easily tune this enclosure by changing the position of the hole on the rear and blocking the last part of the line.

  • 106.588
  • 79.941
  • 26.647
  • 106.588
  • 133.235
  • 26.647
  • 133.325
  • 26.647
  • 133.25

= 771, near enough to the 720mm that I want!

I now have an enclosure that’s 170mm tall by 200mm deep by 190mm wide. 6.4 Liters. Can’t see really how I can reduce the outer size by much more than this…..
