Fan protective grille

• The Hackerspace main network switch was quiet noisy.
• Original 40 mm internal fan (5 Volt) was replaced by an external 70 mm & 12 Volt model.
• Running at 5 Volts keeps it at a lower noise level.
• To avoid (further) hurts, the fan needed a grille.
• OpenSCAD Script Datei:Fan-Protector 005.scad
  • → render mesh and export in STL format
    • → 3D print on yag-freak's Prusa Mendel - thank you!

Ruler for debugging

Screenshot

• add a simple ruler to OpenSCAD source code
• optical control - prevent getting lost of orientation and size of the result
• ruler will not be part of STL output etc. (using the % background modifier)
• Source: Datei:Ruler for debugging.scad

//
// rulers - demo
//

# translate ([60, 30, 50]) cylinder (h = 30, r=20, center = true, $fn=30); // sample, only - add your objects here


ruler_grid = 10;  // mm
ruler_digits = 10;
ruler_thick = 0.5;
ruler_length = ruler_grid / 4;

for ( i = [0 : ruler_grid : ruler_grid * ruler_digits] ) 
{
	% translate ([i, 0, 0]) cube([ruler_thick, ruler_thick, ruler_length], center=true);
	% translate ([0, i, 0]) cube([ruler_thick, ruler_thick, ruler_length], center=true);
	% translate ([0, 0, i]) cube([ruler_length, ruler_thick, ruler_thick], center=true);
