Description

Overview:

This model has only three differing parts: A right and left arm/segment (1&2) and a four-point joint connector. Each arm has an extruded profile on each side which was made to allow the maker to differentiate between arms/segments. These will only connect to each other on the flat back side of each arm/segment.

This model also takes advantage of the use of your scrap filament for its hinges/connection method. All connections are also press fit into place and require no glue for assembly. Alternatively, you can also use a *soldering iron to further secure each connection but this is not entirely necessary for my model.

I'm aware there are existing Hoberman Spheres available on various websites but I aimed to make one similar to Siberk's Cuboctahedron style version on Thingiverse.

This kit has quite an assembly process so be ready to work with small parts, pliers, a flush cutter, screwdriver or small metal rod (used to press filament into place), filament bits and a hard surface. Total time for assembly was about 3 hours but expect a longer time if you struggle with small part assemblies.

What You Need for this Project:

Tools

  • Pliers
  • Flush Cutters
  • Calipers for Filament Scraps (you can test fit and eyeball as well)
  • Screwdriver or similar (something with a small metal tip)
  • A hard surface
  • (*Optional) Soldering Iron

Printed Kit Cards

  • 1x - Main Ring 1
  • 1x - Main Ring 2
  • 2x - Mid Section 1
  • 2x - Mid Section 2
  • 2x - Triangle 1
  • 2x - Triangle 2

Printing all these cards with yield 48 of each arm/segment for a total of 96 arm/segments and 24 4-Point Connectors.

 

See the attached PDF for assembly.

 

I hope you enjoy this new iteration of the Hoberman Sphere!

printed great in petg. Very challenging and time consuming to put together but I eventually got it.

Glad it printed well in PETG for you, and yes this is a very time consuming project. I'm glad you stuck with it and got it done, I very much applaud you for that hard work!

Replying to @3DVJModels :
I actually ended up putting in a few extra hours on it as I found some slight mistakes I made in assembling it the first time. working great now. I’m not sure if I’d make another one but I loved the challenge. haha

This design wouldn't stick to my A1's bed for some reason... But this concept looks very cool!

I appreciate you attempting my print profile. Just some things to keep in mind, bed adhesion is usually user error as this model has been tested on all Bambu Lab build plates. Be sure your build plate is free from any fingerprints or oils. Also, to find success you will find adding a fresh layer of glue (or any build plate adhesive) will provide a better surface for your parts to print on. I hope you understand and I thank you for bringing this to my attention.
