Hehe, I’ve no idea what it’s all about either, I just copied it & pasted in into Openscad & hit render

Nice job for tomorrow, thanks Alwyn

And with support material

Following the request from Wayne I have done a front wheel that matches the outside of the rear wheel and here it is




and the scad code

module hub () {
difference () {
union () {
translate ([0,0,-3])cylinder(h = 18, r = 17, $fn=80);
translate ([0,0,-3])cylinder(h = 1.5, r = 19, $fn=80);
translate ([0,0,13.5])cylinder(h = 1.5, r = 19, $fn=80);
translate ([0,0,0])cylinder(h = 1.5, r = 21.5, $fn=80);
translate ([0,0,10.5])cylinder(h = 1.5, r = 21.5, $fn=80);

}

translate ([0,0,-3.5])cylinder(h = 19, r = 15.5, $fn=80);

}
// difference () {
// union () {
// translate ([0,0,9])cylinder(h = 2, r = 17, $fn=80);
// translate ([0,0,10.5])cylinder(h = 2, r1 = 10, r2=9, $fn=80);



// }
// translate ([0,0,-3.5])cylinder(h = 19, r = 4, $fn=80);

// }

// translate([4,-1,1]) cube ([13,2,8]);
// rotate ([0,0,120])translate([4,-1,1]) cube ([13,2,8]);
// rotate ([0,0,240])translate([4,-1,1]) cube ([13,2,8]);

}

module hub_centre () {
difference () {
union () {
translate ([0,0,0])cylinder(h = 12, r = 4.5, $fn=80);
translate ([0,0,12])cylinder(h =3, r = 4, $fn=80);
}
translate ([0,0,0])cylinder(h = 16, r = 1.3, $fn=80);
translate ([0,0,11])cylinder(h = 16, r = 2.7, $fn=80);
}
}
module double_wheel () {
// difference () {
// translate ([0,0,-3])cylinder(h = 18, r = 17, $fn=80);
// translate ([0,0,-3.5])cylinder(h = 19, r = 15.5, $fn=80);

// }
difference () {
union () {
translate ([0,0,9])cylinder(h = 2, r = 17, $fn=80);
translate ([0,0,10.5])cylinder(h = 2, r1 = 10, r2=9, $fn=80);



}
translate ([0,0,-3.5])cylinder(h = 19, r = 4, $fn=80);

}
translate([4,-1,7]) cube ([13,2,2]);
rotate ([0,0,120])translate([4,-1,7]) cube ([13,2,2]);
rotate ([0,0,240])translate([4,-1,7]) cube ([13,2,2]);

difference () {

translate ([0,0,11])cylinder(h = 8, r = 17, $fn=80);
translate ([0,0,10.8])cylinder(h = 8.5,r1=13, r2 = 17, $fn=80);
}

}


module axle (){
translate([-3,-1.5,-0.1]) cube ([6,3,10]);
rotate ([0,0,60])translate([-3,-1.5,-0.1]) cube ([6,3,10]);
rotate ([0,0,120])translate([-3,-1.5,-0.1]) cube ([6,3,10]);

}

//translate ([ 0,0,-12]) hub () ;
translate ([ 0,0,10]) hub () ;
double_wheel () ;
difference () {

hub_centre ();
axle();
}

This wheel is going to be difficult to print and I suspect won't function well with the steering, but there it is.

You may have to add supporting material to get it to print. It will be useul or any of you wanting to do a deuce and a half.

Have fun
Alwyn

[midlife306]

Thanks Alwyn, I’m sure I’ll enjoy this, I’ve just set my printer going on the first set of wheels on a 0.2mm layer height, hopefully I might get time to print one of these later today

Just in case anyone wants to do a deuce and a half with lego tyres, here's the front hub



and the scad code


module hub () {

translate ([0,0,-3.5])cylinder(h = 19, r = 15.5, $fn=80);

Found a blueprint of the deuce and a half and the front wheel sits in the centre of the two rear tyres so no need for a fancy offset font wheel.

Hi machine, have a look on the previous page, I’m printing a set now, just waiting for the Lego tyres to arrive.

Just spent the best part of an hour trying to remove the support material, getting it out of the outer grooves is virtually impossible, thrown the towel in.
Plan B....

One printing now

Hi If you can get hold of them ,the M16 halftrack tyres are spot on for the deuce and half.
