Hello,

I was wondering if anyone knew if it is easier to print with flexible filaments in a size 3mm or 1.75mm?
Another question I had was if I purchase thePrusa 12" i3v Kit (V-Slot Extrusion)

3D printer kit from makerfarm and also purchase the Itty Bitty Double Extruder Hardware Set

which requires an extraHexagon Hot End

what voltage should the heater be for the hexagon hot end be that works with the Prusa 12" the options are 12V and 24V
The final question I have is does the Itty Bitty set come with the files to print the parts that are not included?
Any help is appreciated I am new to the 3D printing world
