This is a modified version of Hoeken's Coupling. I've improved the heuristic for the placement of the cutout for the screw nuts to work fine with a wider range of parameters and changed this cutouts geometry to a cubic form.

I've also added some epsilon-magic to make the OpenSCAD CSG preview for the design look pretty (see screenshot).

This is a simple design for a parametric lasercut desktop filing rack in OpenSCAD.

This is an OpenSCAD script to generate DXF files for QF breakout boards. The script conains parameter sets for Xilinx VQ44 and Xilinx VQ100 packages.

This is a lasercut design of a Leitner's learning box for flashcards.

This is an OpenSCAD Model of minds SpiderBot. The servo positions are design parameters. So you can change them and watch the SpiderBot moving. There is also some infrastructure to animate the spiderbot using OpenSCADs animate view mode.

The most recent version of this model can be checked out from the svn repository:
svn.clifford.at/handicraft/2010/spiderbot/

an improved version of random's sphere thingi. I've cleaned up the code to use csg for creating the rings and added colors because random mentioned in his thingis description that the original part had each spehere in a different color.

A set of lasercut wooden objects for teaching the decimal system.

Small cubes (1x1x1) for 1, sticks (1x1x10) for 10, squares (1x10x10) for 100 and big cubes (10x10x10) for 1000.

I wrote a script to generate lasercut boxes. The script reads a config file with the box dimensions and generates a DXF file and an OpenSCAD model. We use the script for all types of cases here at metalab. The example file attached is the case of our electronic door lock system.

The script can be found here:
svn.clifford.at/handicraft/2009/boxgen/

You might need to install SPL (the scripting language I've used for the script) before you can use the script:
clifford.at/spl/

A simple lasercut cashbox I've designed for the lasercutter fees at metalab, vienna (http://metalab.at).

A small python script for generating DXF designs of involute gears.

Without an output file the generated gear is displayed in a (tkinter) window instead of generating a DXF file.

The script is licensed under the terms of GNU GPL. This however does not have any influence on the DXF files you generate with it..
