I came across one beautifull model here at MakerWorld, which I printed and was so stunned with how beautifull it was.

The art is nice as a valentine´s gift. One thing that I did not like about the original model was the amount of the waste and filament changes.

The original had was over 11g of waste and 19 filament changes, which I reduced to only 2g of waste and 6 filament changes so -75 % less waste and a lot of time saved :) . The saved filament is from the inside of the model, which kept changing the colour for layer, that you do not even see. I could have just repaint the model from the slicer, but it would still print the “previously multicoloured” parts, but black. So I decided to change the model itself.
