This is an OpenScad script to generate modular and parametric racks, for a printable rack & pinion system for Reprap 3d printers, as a replacement for belts or threaded rods.
More info here : http://www.kaosat.net/?p=1670
Please note that this is an experimental , work in progress version
-Added the herringbone version , in wich you can set the center angle (see schematic), that script can also generate the straight teeth with an angle of 0
-this version is cleaned up and optimized, and much faster to compile so please use this one preferably
-i haven't printed this one yet, and i am not 100% if all is ok
-just a short video of a very very basic "platform" movement test : http://www.youtube.com/watch?v=8_KtJL7Gmto
-for testing simplicity, the motor is on top , but would ideally be underneath the platform
-i will try to have the herringbone version finished by next week
Please don't use the attached stl file , as it is just an example, you will need to use the OpenScad (http://www.openscad.org/) script to generate the stl files
For usage instructions please see info in the openscad file
I used this http://www.thingiverse.com/thing:3575 very nice script to generate the pinions
