Random laser pointer cat toy

I designed it because my cat loves laser and never has enough of it. It creates almost random ( there is a cycle) movement for laser pointer.

Please be careful where you point the laser. Point it down to avoid eyes.

Design goals were:

• make it mostly 3d printed (as DIY as possible)
• as little parts as possible
• simple materials you have or can buy in any hardware store

Parts needed:

• 3D printed parts
• 0,6mm insulated copper wire
• 9g servo
• 3 AA batteries
