Mbot 3D upgrade, Laywood example

I bought a Mbot 3D printer for the money I got when I sold my Butterfly bitcoin asic:s, I think it was in january.

For a week ago I get an email about an Upgrade kit for mbot cube to mbot grid so I order it.
and whats happen? I need to wait untill tuesday!!!.
I hate to wait on my free time...
If you wonder what a mbot is. Take a look here (they also have PLA for a good pice)
It's working good for the price! I will send update on the Upgrade process.

Two awesome Cars in laywood!
They smell like wood.

I recommend laywood for all 3D printer startes, it's SO easy to print with, but the thread easy breaks!

can it be a good idea?

If I hade a 3D printer. Then i had print a waterpump.
If I hade a hygrometer to detect if the flowers need water then I whould use an arduino to...

yeah! of curse automatic plant "feeding".

Whait ?! yea a had a 3D printer. so, next project. when I receive my hygrometer. is time to do an automatic plant feeder.

I will post my code here when it's done. maybe do a Youtube video also. should a do a video?
