Hi Guys

This as a project to collect in one place the best expansion to add on your Otto starter

There is nice collection of them directly in the ottodiy.com website

Bonus here are some cool gadgets to pimp your robot

Other remixes with cool decoration that you can reuse 

Please reply if i miss something I will be editing as they come so is always updated

I just start by attaching the .STP files of the expander template, oled and led matrix that @Bill SCHONFELDER asked for

I will be adding also the STL or links to them
