Ah i already had a feeling that you would do 4 extruders on it since i just seen your Logo on your avatar.
Its just that i didnt see one on your printer that was shown above,

I would kinda...

I meant to perhaps get a second Hotend on it so you can use 2 diffrent materials/colors etc.

Well it could print PLA, but ye without heating element it will be still tricky :P

for that price they could have been more complete.
Also perhaps a few extra hotends attached.
