Armillary Sphere

# Armillary Sphere

## Parts needed

* 109mm long steel axle with an diameter of 2mm
* 2x 682ZZ ball bearings
* CA glue

## General hints

* I designed this model as a one-time build, so it is not optimized and can require some sanding to make all parts move smoothly
* The parts are relatively fine and it can take some skill to align and glue them together
* Parts that need to be printed twice have an _2 at the end of the filename
* Printing is quite easy for the most part. The only challenging parts are the earth_meridans that are complex, thin and need supports.

## Assembly

### Foot/Holder

For the base you need:

* Foot_base
* 2x Foot_Left
* 2x Foot_Right
* Foot_Horizon

The 4 foots can be sticked and glued in the base. After this the horizon can be applied on top. There are small pins that help you allign the horizon correcly.

### Earth

This is the central and rotating part. For this you need

* 2x Earth_half
* 2x Earth_meridian
* Earth_zodiac
