GuardBot Improvements

### Improvements for the GuardBot

**What?**

I noticed some lacks and bad designs in my GuardBot. So I had to fix them. Also the servo controller needed some holder.

**Building it**

All the screws are size M3 with variable lengths between 12mm to 30mm. **Tip:** Use nyloc nuts where ever possible.
