TwinTeeth Basic - How to get it
The materials used to build TwinTeeth are very easy to find in any hardware store, electronic store and/or over the Internet.
Open-Source
TwinTeeth is an open-source project for both: hardware and software. You will find here all the blue-prints, bill of materials and source files.
You can distribute, copy and modify it under the terms of the Creative Commons Attribution-NonCommercial 4.0 International License.
We have designed and tested TwinTeeth with much effort in the hope that it will be useful to the community, but WITHOUT WARRANTY OF ANY KIND; tacit or implicit to no particular purpose.

Blue Prints
You can download the drawings of the project in Autocad 2006 file format here: TwinTeethBluePrintsV1.31.zip
Version 1.3 includes the lead-screw modification we mentioned in the blog article.
If you don't own an Autocad license, maybe you can use FreeCad to open the file. You can convert them to FreeCad format using this utility. You can also open the DWG files directly in FreeCad if first you import the utility in it. See FreeCAD and DWG.
Anyway you only need the drawings if you want to modify the design because TwinTeeth is very easy to assemble and the tutorial show you how to do it step-by-step.
Printed Parts
Below you will find the list of printed parts. They can be downloaded from here TwinTeethPrintedPartsV1.31.zip
Version 1.3 or above includes the new parts we mentioned in the blog article.
How to print the 3D parts
We used a RepRap Prusa I2 3D printer with a hot-end J-head, a 0.35mm nozzle and 1.75mm PLA filament, but any other configuration is also valid. Most of the pieces have a 20/40% infill. We recommend using speeds of 30-60 mm/sec, although this depends on the printer model.
You can use any slicing program: Cura or Slic3R.
