Thought this might be useful for others here.
I have been messing around with openScad making thing's for other projects, made up some circuit board mounts and then these stand off pieces.
These are 12mm high and will fit an average M3 nut firmly in the top...knock it in with a small hammer.
This is my first public post of this Scad stuff, only new to cad work and still lots to learn, so if it looks all untidy and sloppy....so be it. 
$fn = 100;
rotate(a = -90, v=[0, 0, 1])
translate([-5, -14, 0])
difference(){
cube(size = [9.8,12.5,10], center = false);
translate([-1, 0, 2.2])
rotate(a = 20, v=[1, 0, 0])
cube(size = [12,20,10], center = false);
translate([5,5,-.1])
cylinder(r = 1.6, h = 4 );
translate([5,5,2.2])
cylinder(r = 4, h = 8 );
}
difference(){
color("Blue")
//Change hight 5 to 20
cylinder($fn = 100, h = 12, r1 = 5.2, r2 = 4.5, center = false);
translate([0, 0, -2])
cylinder(r = 1.75, h = 24 );
difference()
//Hight of nut in stand off
translate([0, 0, 9.8])
//Change these values for nut size.
cylinder($fn = 6, r = 3.2, h = 4.1 );
//An M3 Nut fits tight as is, or adjust if needed.
}

The blue one's printed in PLA and the Black in ABS.
Feel free to modify it to suit what you want, and I would be pleased if people would add a few more if they like, as long as this stays within the topic of parts for electronics.
Cheers Aaron

This is a mount for these little Ac to Dc 12v converters, As they have no screw holes in them its no problem to pinch it at opposite corners with screws and non conductive washer's.

Will be using these on the next inverter and should make the setup a little more neat.
Still learning more as I go, some flow control to cut down on repeating code, so its a little less code now than when I started this one but it works ok and that's what matters.
$fn=50;
difference(){
hull(){
//bottom section.
for (a =[1,25])
translate([a,4,0])
cylinder(r = 1, h = 2);
for (b =[1,25])
translate([b,52,0])
cylinder(r = 1, h = 2);
for (c =[0,56])
translate([13,c,0])
cylinder(r = 4, h = 2);
}
{
translate([13,0,-.1])
cylinder(r = 1.3, h = 3);
translate([13,56,-.1])
cylinder(r = 1.3, h = 3);
}}
//top section
difference(){
translate([5,12,4.4])
cube(size = [6,6,5], center = true);
translate([5,12,4.4])
cylinder(r=1.1,h=10, center = true);
}
difference(){
translate([21,44,4.4])
cube(size = [6,6,5], center = true);
translate([21,44,4.4]) cylinder(r=1.1,h=10,center = true);
}
difference(){
minkowski()
{
translate([1,4,0])
cube([24,48,8]);
cylinder(r=1,h=.5);
}
minkowski()
{
translate([3,6,-.1])
cube([20,44,9]);
cylinder(r=1 ,h=.5);
}}
translate([4,44,4.4])
cube(size = [4,6,5], center = true);
translate([22,12,4.4])
cube(size = [4,6,5], center = true);
//Cheers Aaron.
The first print works ok but required some adjustment of the hole size, the corrections have been made.
Also I have some gaps around the mount holes, as it happens that's part of the slicer software that I was not aware of, apparently I have been using the printer without any top surface skins, so now (with 4 on) some of my other prints might have some improvement after correcting this, will find out some other day.
Cheers Aaron

This is for the Daly BMS Light Bar, SOC and activation button.
It could do with a clear plastic cover over the the front to keep the bugs out.
The PCB is small and bare, really needs some sort of protection, Some are sold already in a plastic case, just not all of them.

Large terminal cover,
As it is it will fit a stud with a height of 28mm and a nut of 20mm diameter.
Easy to change if needed.
//Large Terminal Cover
$fn=50;
difference(){
union(){
//Outer size, change if required, width of nut and height of stud.
translate([0,0,24])
sphere(13);
cylinder(r=13 ,h=24);
translate([0,0,13])
rotate(a = 90, v=[1,0,0])
cylinder(r=9 ,h=35);
translate([-9,-35,0])
cube([18,40,12]);
}
union(){
//Inside size, change if required, width of nut and height of stud.
translate([0,0,22])
sphere(10);
cylinder(r=11 ,h=22);
translate([0,0,13])
rotate(a = 90, v=[1,0,0])
cylinder(r=7 ,h=35);
translate([-7,-35,0])
cube([14,40,14]);
}}
//Cheers Aaron
Makes the job look a little more neat and tidy, also keeps the wildlife off the terminals....How do I know this.
This setup is the terminals between the 48v batteries and the inverter.
Cheers Aaron

Cable Tie down,
Very handy for larger cables or a bunch of small wires, I have made and used quite a few of these, have used double sided sticky tape in some places, but others will be screwed down in place, screw hole provided.

Very clever Chappie, our Aaron.
Encouraging early results with the Li. Po pack. I liked those battery terminal covers ,they are difficult to purchase. And you made them in red and black .

Thanks Guys, Always happy to share.
Parts are easy to modify if needed.

Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.
