Printable Lighning

Nikolaus Gradwohl2011-02-12T09:50:00+00:00

I made a lightning bolt to test the openscad polygon and linear_extrude functions.
To define a polygon you have to define a set of 2D-coordinates and some sets that define the paths. In this example only one path is defined that connects all the points. Then I extruded the polygon to make it 3D and centered it using translate, to make it printable.

translate(v=[0,-45,1]) {
    linear_extrude( height=2, center=true)
    polygon( points = [[-5,0], [15,40], [5, 55], [20, 75], [0, 90], [-15, 55 ], [2, 36]],

Generative Battery Compartment

Nikolaus Gradwohl2010-12-06T10:09:49+00:00

I need Battery compartments for many of my electronics projects and buy them usually in various sizes, but since i have a makerbot I am thinking about how to print them myself. So I just wrote a openscad-script that generates battery compartments. It handles various battery types from AAA to D and can generate compartments for even and odd battery numbers.

Download the OpenSCAD file enter the type and number of batteries you need and generate a stl file. Then either add it to your model or use it as a standalone compartment. The only thing you need to add (besides batteries) are litte metall stripes for the contacts.

Battery Compartement 2 AA batteries 4 AAA batteries

My boss asked me to clone myself several times, so i started by making a little 3d figure in blender and printed it on my Makerbot. Not quite a clone of me, but every journey begins with a first step :-)

Custom Cookie Cutters for the Makerbot

Nikolaus Gradwohl2010-06-27T19:34:00+00:00


there is a new version of the CookieCutter-Editor!

Recently some very awsome cookiecutter-designs started to show up on thingiverse (like the escher cookie cutter or the jigsaw cookie cutter, and many more) (and one of the local radiostations has played "last cristmas", because it's only 6 months till x-mas O_o )

So i thought about how the generation of such custom cookie cutters could be simplified and i developed a custom cookie cutter generator in processing.

Click here to download the processing sketch.

Basically it's a very very simple vector graphic programm, where you can design the cookie form you want to have. to export the design as a stl file press the letter 'e'

This is what the cookie-cutter-editor looks like
