New SCR holding brackets and firing circuit board

Finally got the new brackets printing. They're far simpler and I'll need another kind for the new circuit board (now that I've got the printed version) as well as the big ass resistors that board uses.

As you can see I've also got new black plastic on a spindle so the makerbot can just feed and build nearly forever.

That machine was a great investment. The objects are cheap (essentially free) and surprisingly durable. I actually put one on the strong table I've also got my milling machine and started hammering it; it doesn't even show damage. I'll do an official tensile strength test at some point.


Code for the part:
frontNeck = 4.5;
rearNeck = 13;
scrWidth = 18.2;//16.8;
scrHeight = 15.5;//14;
scrFitDepth = 20;
boltDiameter = 8;
boltNutWidth = 12.5;//11;
boltHexWidth = 7.2; //tan(pi/6)*boltNutWidth
boltNutHeight = 5;
boltCarrierRadius = 6;
boltToScrDistance = 6;
//fitDepth = 10;
totalLength = 33;//43;
wallThickness = 3;
bedToBoltCenter = 18;

module circuitHolder()
{
difference()
{
union()
{
translate([totalLength/2,0,-bedToBoltCenter/2-scrWidth/4-wallThickness/2+scrWidth/2+wallThickness])
cube([totalLength,scrHeight+2*wallThickness,bedToBoltCenter+scrWidth/2+wallThickness],center=true);
// rotate([0,-90,0]) //bolt
// translate([0,0,-wallThickness/2-boltNutHeight/2])
// cylinder(h=wallThickness+boltNutHeight,r=(boltDiameter/2+boltCarrierRadius),center=true);
//translate([totalLength/2,scrHeight/2+wallThickness/2,-bedToBoltCenter/2+boltCarrierRadius])
// cube([totalLength,wallThickness,bedToBoltCenter+boltCarrierRadius],center=true);
//translate([totalLength/2,-scrHeight/2-wallThickness/2,-bedToBoltCenter/2+boltCarrierRadius])
// cube([totalLength,wallThickness,bedToBoltCenter+boltCarrierRadius],center=true);
}

{

translate([scrFitDepth/2+rearNeck/2+boltNutHeight+wallThickness+boltToScrDistance,scrHeight,0]) //horizontal slots

rotate([0,45,0])
cube(size=[15,300,15],center=true);
translate([totalLength/2+1+boltNutHeight+wallThickness,0,0]) //main SCR holder
cube([totalLength+2,scrHeight,scrWidth],center=true);
rotate([0,-90,0]) //Bolt
cylinder(h=100,r=boltDiameter/2,center=true);
