Glowglobe from Villeneuves Dune (2021)

This is the final version of my take on the iconic Glowglobe from Villeneuves Dune. My original work-in-progress version was uploaded on Thingiverse before (https://www.thingiverse.com/thing:5397910). This revised version is optimized in terms of the groove that fits the translucent rings and has a better internal geometry on the “ornament”, requiring less support material. Furthermore, a hole was added to the inner ring to allow a cable to pass through for illumination. 

The Glowglobe was modeled after this picture that I found on Twitter:

The stand is an original design by me, inspired from the geometrical elements of the Globe. It contains a slot at the underside to feed a cable through.

I printed the Globe on a Bambu P1S with 0.18 mm layer height and a 0.6 mm nozzle. The ornament, inner ring and stand were printed with Sunlu Matte Black PLA and you only need supports for the very outer edge of the ornament. The translucent rings were printed in vase mode from Polymaker Transparent PETG. Be aware that you might need to do a test print of the translucent rings to make sure that the version with your specific filament has the actual dimensions to properly slot into place (e.g. due to material shrinkage and potential under- or overdimensioning of round objects by your printer).

I added a 5V Ikea “VATTENSTEN” Led Strip to the inside and fixed it to a generic cyclinder that I glued inbetween the bottom sides of the ornament. Furthermore, I used a diffusive sheet to make the illumination from the inside smoother and get rid of highlights. I think this can be still improved by using a more evenly lit led strip and the diffusive film is probably also not needed when a higher-quality light source (potentially also dimmable) is employed.
