3D-Printed interlocked rings

Nikolaus Gradwohl2010-05-25T19:56:00+00:00

Today i printed some interlocked rings on my makerbot. I used openscad to generate the stl file. The two rings are standing in an angle of 60 degrees and don't touch each other

Nikolaus Gradwohl2010-05-20T10:35:00+00:00

A friend of mine is currently renovating his VW-Oldtimer. For one of the windows two little plastic parts are needed, but he could only get one :-/

so i designed a replacement part in openscad and printed it on the makerbot

there is the stl and the openscad file

Last Friday I got 20 little cacti, but I had no matching pot saucers. So i started my 3d Printer and made some.

Printed Processing sketch

Nikolaus Gradwohl2010-01-13T06:05:00+00:00

I just printed the first stl file that i generated using a processing sketch.

I used the unlekkerlib to export a stl file from a sketch that generates simple 3d spiral, used blender to add a socket and printed it on my makerbot. Skeinforge complained about some invalid triangles, but beside that it worked surprisingly well.

This is what it looks like in blender rendered

and this is what the makerbot made of it printed

and this is the processing-sketch i used to generated the spiral

import unlekker.data.*;

void setup() {

void draw() {
  for( int i =0; i < 100; i++ ) {
    for(int a=0; a < 36; a++) {
      float r = 10 - map(i,0,100,0,10);
      vertex( r * sin( radians( a * 10 )) + sin(radians(i*10)) * 10, 
              r * cos(radians(a*10)) + cos(radians(i*10)) * 10);

      int j = i+1;
      vertex( r * sin( radians( a * 10 )) + sin(radians(j*10)) * 10, 
              r * cos(radians(a*10)) + cos(radians(j*10)) * 10);

Today i managed to make a scan using my conmark L2000 3D-Scanner that looks at least similar to the object i tried to scan :-)

it's not quite what i hoped it to be yet, but at least it's a start.
