These holidays, we're spreading the holiday cheer with a Marvin Christmas Globe! Marvin is the symbol of the 3D Printing movement and his core ethos is about community, creativity, social change, and problem solving. He's determined to revolutionise the way we make things through 3D Printing.
This model is meant to be printed hollow. This way it only consumes 10 grams of filament, and will print within the hour. In order to get the best results, a layer height of at least 0.15 is necessary, because there are a few parts that are close to horizontal. The design of the Christmas Marvin is optimized for Ultimakers, but will print on any other FDM printer as well. Make sure you put the model upside down, and don’t fill the bottom.
Because of the coned shape and hollow print it is important to print at a low speed and temperature. This way the print has enough time to cool down and won’t warp/deform. For the middle section the speed/temperature may be increased.
There are also hooks for the Christmas Marvin, so you can actually put them in your Christmas tree.
Everything is optimized in order to print as many Christmas Marvins as you want. There is even an automated G-code (for Ultimakers) that will continuously print 50 Marvins.
