2019-03-28 Added a split Version of the large Turntable Base (designed by Paul):
I am very happy that some very skilled people developed and published a CNC-Version of the scanner, that can be seen and obtained in the following German-Speaking Forum: https://www.cnc-aus-holz.at/index.php?thread/1057-3d-scanner-openscan-eu/&postID=12398#post12398
There have been several very interesting remixes with added compatibility to the ramps board, so check it out here: https://www.thingiverse.com/thing:3482715
2019-01-03 Added a larger Version for the Turntable Base (35cm) for those with a larger printer ;) Thanks to Jan G. for the modification
2018-11-25 There is a website, where I will bundle all the information on the 3D Scanner, feel free to visit http://www.openscan.eu
2018-10-11 Finally, I am able to publish the tested and well functioning circuit boards + programm code for the arduino. I added some pictures of the PCB/Breadboard wiring and you can download the sketch from the following link: https://drive.google.com/open?id=1HvSOB2VEg-s1xDzMar10pRFFcg8bUeEp
2018-08-18 New Version of the Turntable-Base with a cable slot for smaller Nema17
A fully revised and tested version of my first 3D Scanner built. This version is compatible with Smartphones and DSLR Cameras and uses photogrammetry to create high-quality 3D Models of your object.
I am working on various videos describing the functionality of the device. There are several videos describing the Scanner and it's functionality on my youtube Channel
Furthermore I show the whole workflow from pictures to 3d Model with freeware only (Sorry, some videos are in German): http://www.youtube.com/channel/UCG3IgwSIFFlc77Luf9VVlYw
The parts are printable without support.
You should print one of the small gears first, in order to check the tolerance and if they fit on your Nema17 shaft. If not, you can increase the extrusion rate/flow until the gear has a tight fit on the shaft. I have printed these parts with slight overextrusion in order to make the layers bind better.
