3D model description

The inspiration for 'The Geodesic Sphere' lamp shade stems from the ancient Greeks' love of geometry. Although it isn't strictly a Platonic Solid it feels like a continuation of this family of 3D shapes.

This 3D printed lamp shade is huge! A sphere of 40cm in diameter, it will become a feature of even very large rooms. It is made up of 17 printed components, 2 Pentagons, 5 Diamonds and 10 Hexagons [see accompanying build instructions for more details on assembly and components].

The design takes advantage of the 3D print process to create large, strong hollow parts that weigh a lot less than you would think [Assembled the Sphere is less than 900g], therefore it is safe to hang on ceiling lamp wire without reinforcement. Ours has been hanging for over a year and has survived a mild earthquake!

This product has been designed for an E27 lampholder [40mm diameter] if you can't find one of those let us know and we can supply you with an adapter plate/alter the design.

We have tested this product for over a year with a 15W light bulb and there has been no deformation of the PLA. If you use PLA we wouldn't recommend going much higher than this.

Printed with Satin Shine + White PLA [Real Filament]

To print this design we used an Ultimaker 2+ 3D printer with a 0.6 mm nozzle [You can also use a 0.4mm or 0.8mm].

Dimensions for Each Component

Gd Upper Pentagon: 200mm x 191mm x 22mm

Gd Lower Pentagon: 200mm x 191mm x 35mm

Gd Hexagon: 210mm x 205mm x 42mm

Gd Diamond: 174mm x 119mm x 15mm

We would love to see your prints!!

For those in the US, it looks like #8 x 5/8" screws are the comparable Standard size

Bonjour! The quantity of PLA for all the prints is 880gr.

Bonjour, quelle quantité de PLA faut il compter pour imprimer l'ensemble des pièce ?

Hello, what's the quanyity of PLA used to make all the prints?
Thanks you.

No worries! If you have any other questions just let us know :)

thank you

Hi Faustinn3
You can scale it down, if you find a smaller light fitting than an E27 (40mm Diameter), also you might want to change diameter of the screws from 4mm to 3mm depending on how much you scale it down.

my 3D printer is too small for this print, but I would still like to realize it, is it possible to reduce the size of the pieces or does this pose a problem?
(sorry for my english i use google trad)

Yeah slicers can be erratic sometimes! Glad to hear its working well now. Enjoy the build!

I definitely had it placed on the correct face but as an exercise I closed and re-opened my slicer (which had been running for many days) and tried again. This time the part worked as intended so I believe it was just a bug or memory issue in the slicer. Thanks for including the build guide. I was able to download the package again and retrieve it!

I see, we have just checked the file in our slicer [Cura] and found no issue. It sounds like you might be attempting the print on the wrong face, try turning the part 180 degrees and give it another go [see print orientation images on this page]. Failing that send me an email at to troubleshoot further. Also apologies about the build guide we have fixed that issue now. If you can't access it drop me an email and I will send it to you. Hope it helps, we would love to see your completed print!

You bet! The part experiencing the problem is GD Diamond.stl. The other parts are all printing fine. Yes, I used PrusaSlicer to set the flat face onto the build surface. The issue is along the thicker middle spine the ends are just slightly raised. I can experience this in the printed parts as well, they rock a bit on a flat surface. Also, one other thing that would be great if I can get from you. The writeup mentions "Notes: If you are having trouble with the build please look at the provided build instructions. Geodesic Sphere Build Instructions.pdf" but no PDF was included with my download.

Hi! Thanks :) In which pieces/areas of the print did you have to use supports? did you try using the "level to bed" feature in your slicer? If you can provide any more detail we are happy to troubleshoot with you.

Very cool model though my slicer needed to use supports as certain pieces don't sit flat on the bed. FYI
