A bicoloured placemat. Printed on a Velleman K8200.Using Repetier Host 1.6 Print bed 200x200. Pause at place where pattern starts to change colour. The files are for Left hand orientation. Opposite hand can be made by mirroring in the host.
Velleman K8200 modified for 1.75 filament
Filament change procedure in my website jandani.com
Designed in Blender. One segment traced out using bezier curves, Then duplicated and rotated to fill 360 degrees and form the solid lower part of the mat..
One segment of the pattern traced out with Bezier curves. Again duplicated and rotated . Similarly with the cylinder pattern in the centre.
Three parts placed together to form the basis for the print file
The case made by using the solid part of the Mat file, expanding in X and Y for base. Copy base twice and reduce one copy in X and Y and expand in Z. Subtract inner from outer to make wall using Boolean difference. Extrude in Z to give wall height
