DetailsYou must send me your core - I will upgrade and send it back. Includes one upgraded core and 4 nozzles. .25mm .4mm .6mm .8mm Other nozzles (including 0.5mm steel or .15mm brass) sold separately. If I run out of red heatsinks you might get a gold one instead.
Normally I program these up as "Hardcore" but if you prefer for it to say "AA 0.4", "BB 0.4", "AA 0.8", or "BB 0.8" then let me know in an email. The name affects things in a minor way - if it's BB then the printer will only let you select PVA (but that doesn't matter as it's really the slicer and not the printer that sets things like temperature).
