Christmas Chain V1.2 - Ringchaku Ring.stl

Chain Link Klein Bottle

This model uses chain link latticing to represent a three-dimensional approximation of the four-dimensional “Klein Bottle.”

See here for video: https://youtu.be/AWJ-R3GBT80 

The concept of a Klein bottle was first described in 1882 by the German mathematician Felix Klein. It is a closed non-orientable surface that has no inside or outside. It is similar to the Möbius strip, but unlike the Möbius strip it has no boundaries and cannot physically exist in three-dimensional space.

In this three-dimensional representation, the surface intersects with itself, but in four-dimensional space the self-intersection can be eliminated. Unfortunately, I don’t have a 4D printer yet.

Modelling this intriguing shape in chain link latticing allows for visualization of the whole surface.

Print in place Chain

It prints diagonally across a 220mm x 220mm bed. I usually print with a small brim. 

The chain is designed with flat edges so that no support is needed during the print. If you don't have great bed adhesion, I recommend a small brim only. 

Looks great in gold and silver. Will be designed a connector to chain multiple lengths together.

"Boo" Spinner Fidget Keychain 

A Halloween spinner/keychain made from the word "Boo."  This model prints in place quickly and with no supports needed.  It features independently spinning hoops embedded in the O's of Boo and a built-in hole for a keychain.  I used a multi-color printer to get the different colored embedded hoops.  

**Printing Info:**
**These are just the settings I used to test the model, feel free to use whatever settings work best for you.
- FDM or Resin: FDM or Resin
- Scaling: Can be scaled up, scaling down may not work well.
- Supports: None
- Infill/Perimeters: I just used 10% infill with 2 perimeters, but I would use extra perimeters for more strength.
- Nozzle Size: 0.4
- Layer Height: 0.2

**Printing Assembly:**
Just slice and print, no supports needed.  The embedded hoops in the O's should spin freely.
