What plastic is this printed with?

Is nobody building this on the Replicator 2 using MakerWare?  I've tried everything and it always fills the first layer.

I made a more cleaner scad code for the track, the wheel will come soon. I add the possibility to have mores wheels for larger track, snow blade each x teeth:

r=45 ; // outter radius of track
h=6; //heigth of track teeth

n=50;// nb of teeth of the track keep 9/10 ratio radius/nb of teeth

t=1;//perimeters width

w=15; //track width

ri=7.5;//radius of the internal wheel at least 1/2 of the width of the track

pi=3.14159;

j=1;//nb of internal wheel for large track

tw=pi*r/n;//perimetral size of tooth

b=0;//blade each teeth -for snow track, keep integer ratio with the number of teeth set to 0 for none

sb=3;//size of the snow blades

union(){

linear_extrude(height = w)teeth();

linear_extrude(height = w)jante();

for(i=[1:j])

translate([0,0,i*w/(j+1)])scale([1,1,1])rotate_extrude()innershape();

}

module teeth(){

for(i=[1:n])rotate([0,0,i*360/n])

polygon(points=[[r-t,2*tw/3],[r-h-t,tw/3],[r-t,-2*tw/3],[r-h-t,-tw/3]],paths=[[0,1,3,2]]);

if (b > 0)

{

for(i=[1:n/b])rotate([0,0,i*b*360/n])

polygon(points=[[r-t,2*tw/3],[r-h-t,tw/3],[r-t,-2*tw/3],[r-h-t,-tw/3],[r-t+b,0]],paths=[[0,1,3,2,4]]);

}

}

module jante(){

circle(r-h);

}

module innershape(){

translate([r-h/2-ri,0,0])circle(ri);

}

hope this help

because the derivative code from the bracelet is a bit messy !
 

Can anyone provide guidance on printing this on a R2?  Using MakerWare?

I see the option to print without infill, but it still tries to print what looks like a bottom layer (before I stop the print).  I don't see any options to not draw a top/bottom layer.

Thanks!

(FYI I'm working on cura/replicatorG but it has it's own list of problems I'm trying to work through just to get it to print anything at all)

What type of servo did you use? Brand and size?

What am I doing wrong - the track is a solid disk?

I made a little modification in the caterpilar track scad file:
to make wider track I made the number of circular bump in the base parametric.

m=50;// number of bendy parts around the circle
nb=3;// number of circular bump on base

internal_radius = 3; //9
 
and made the other modification :

for(i=[1:nb]){

in the module base1 and module base2

so you can increase the width of the track ans add the number of circular bump you need.

I plan to make a ski doo so it is better to have larger track

by the way if a open scad wizard coul explain how to make a transversal fin each 5  zig zag (to increase traction on snow) ....

it coul add some versability to the design

Awesome, I'm glad someone finally made a real tank out of these. People kept suggesting it, but I don't have any motors lying around. Well done.

You took arround 2 hours to make it into the Featured list! Congratulations!!!

By the way, its awesome!

Your design is amazing!!! Congratulations! 

Looking good. I like the one piece tracks. Way less hardware required.

Great!!
