Description of the model

This is a game, similar to chess. We did it in a way, that everyone can play it. There are signs wich represent the different colours. Each colour stands for one movement of the piece.

Each field contains a little magnet.

This model was designed and tested as part of the 3D4VIP project.

Printing instructions and tips

The optimal print settings are highly dependent on the slicer used. We usually use Ultimaker Cura. Six settings in Cura have proven to be favourable, sometimes in combination: (1) Adaptive Layer Height ensures accelerated printing in the areas of the object where details are not important. (2) Make Printable ensures that support is usually not needed because overhangs are “bevelled”. (3) Use Brim to ensure that the print adheres well to the print bed. Brim can be easily removed later. (4) Initial bottom layer a maximum of two or three layers so that the object has a flat surface and warping does not occur. (5) Maximum two or three wall layers to save material. (6) Infill maximum 15%, but six to seven top layers. If printing is done with support structures, other settings are usually required.
