Anet A8 Laser Mount

I've designed a mount for the following laser I bought from Aliexpress:

**newer version now supported another popular module as well!**

I've made it because all the other designs I found required me to removed the entire carriage and and reattach the belts. With this design you only need to remove the cooling fan.
