Introduction

This is a simple model for a 3-axis coordinate system.  
Perfect for when your right-hand-rule is just not enough or when more coordinate systems (like kinematic frames and chains) should be considered. 

Assembly: 
Simply print each model as described below and press in the axes. 
It should be a pretty tight fit.

Print instructions

Print every model as oriented in each file. 
No support or raft.
It might be necessary to slow down the print a bit for the center piece for better adhesion.

Thanks!

Hope you like this model! Feel free to share your thoughts and share a make for me to see :D
