Ho ho ho! These holidays we’re spreading the cheer through the most awesome Christmas globe inspired by Marvin, the symbol of the 3D printing movement. Composed of 2 separate parts - a globe and a hook -, the Marvin globe was designed by @Luuk and is now available for download on Thingiverse 6 for your Christmas delight.
The 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.
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. Note that the awesome Automated G-codes are made by Joris van Tubergen @rooiejoris_nl from Protospace 1, and are to be used at own risk.
Looking forward seeing your Christmas trees Marvinised
Printed at 0.125mm layers with a 0.25mm nozzle in gold PLA. Turned out great! Turns out the gold PLA is translucent with such thin walls (0.3mm), and it looks great with a light inside as well. Really twinkles! and weighs next to nothing (only took 1.1m of filament).
Check out that luminous idea from @kevtl! You can hook up your Christmas Marvin to some lights, and party like it’s 1999. See GIF in the images section.
Sadly, Makerware does not slice it correctly. It can’t print it hollow, and also leaves some voids on the surface. Which slicer do you recommend that I try for this?
