Back to building products. No more fucking around building tools.

The 3D printer is actually doing it's job: I've got a bracket. It turns out the smallest wall the machine can realistically do in this shape is 3mm so that's the size I build the holder to.

I also have the new circuit boards which I've cut and soldered up one of. I waited to print brackets till I had them because I don't know the size for sure till I've got the boards and frankly it's not a big deal to make brackets anymore so I can just do it at the time I need them :).

I did remember, however, that each of the firing boards has a big-fuck 1000kOhm, 10W resistor that it needs. I've re-engineered the brackets to have a holder. I'd print them now but the sis is in the living room reading (the machine squeaks and smells a bit). She'd tolerate it, but this holiday season the gift I'm giving is not-being-a-fucker.

Code of the machine:
circuitLength = 50;

circuitWidth = 36;

circuitDepth = 3;

circuitLip = 3;

bedToBoltCenter = 22; //Distance between the bottom of the barrel holder and the mounting bolt for each barrel section

bedWidth = 40; //How wide the bar that holds the barrel is.

boltDiameter = 8;

wallThickness = 3;

resistorWidth = 11;

resistorTopSlat=6;


//a = 10;

//X is along the length of the circuit

//y is along the barrel length

//z is up

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

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

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

cylinder(h=30,r=(boltDiameter/2+2*wallThickness),center=true);

translate([bedWidth/2,0,-bedToBoltCenter/2-circuitDepth/2])

cube(size=[bedWidth,circuitWidth,bedToBoltCenter-circuitDepth/2],center=true);
