Customizable Tricolor Card Holder
This is the three color version of my customisable business card holder.
To customise this you need to upload two, 150 x 40 pixel, black and white images containing your logo - one for each colour. The logo should be white and the background black. Images will be automatically stretched to fit.
Note: the customiser preview only works when both images are loaded.
When you print it, you need to pause your printer and change the filament color, either manually or using pause @ zPos in Sailfish or with a macro script in GPX .
