New circuit holder is ready

This bracket will get bolted in underneath each of the magnet holders. It should contain both the basic circuits and the large bolt-style SCR that I'll be using.

The code for this one is actually quite dynamic so I didn't bother to measure and plug in the real values. I'll do all that when the 3D printer gets here and I can also investigate the strength of the plastic.

The code:
circuitLength = 60;

circuitWidth = 45;

circuitDepth = 3;

circuitLip = 4;

bedToBoltCenter = 20; //Distance between the bottom of the barrel holder and the mounting bolt for each barrel section

bedWidth = 50; //How wide the bar that holds the barrel is.

boltDiameter = 8;

wallThickness = 3;

a = 10;

//X is along the length of the circuit

//y is along the barrel length

//z is up

module circuitHolder()




union() //Added parts


translate([circuitLength/2+ wallThickness/2,0,0])

cube(size=[wallThickness+circuitLength, wallThickness*2 + circuitWidth, wallThickness*2 + circuitDepth], center=true);

rotate([0,-90,0]) //bolt





union() //Removed parts


translate([circuitLength/2 + wallThickness + 1,0,0])

cube(size=[circuitLength+1, circuitWidth, circuitDepth], center = true);

translate([circuitLength/2 + wallThickness + 1,0,0])

cube(size=[circuitLength+1, circuitWidth - 2*circuitLip, circuitDepth+wallThickness*2+100],center= true);

rotate([0,-90,0]) //Bolt
