Step 1: Stuff you need
The plastic parts where taken from the plastic of the printer, be sure to find some straight sheets a cut them from there.
Step 2: Electronics
I didn't make a custom PCB, I reused the PCB from a previous ible and completed it with a protoboard, I will upload the files for the custom PCB when I finish it.
Step 3: Base
Once out I removed the cartridges and cut the platform in order to make it flat, here is where the board will rest.
Finally add two pieces of plastic in the borders for stabilization.
