Gonna be a real pain, as you cannot direct drive 3mm filament. You need a geared stepper, or printed gears.

You said New sd3? All stock hardware? What hot end did you purchase? I have upgraded my SD3 to the e3d v6 hot end.You will need to print a mount for it.As to the difference between a 1.75 and 3 mm the mounts are the same.

I have a new SD3 and want to explore changing the filament size to 3mm.

I have previously purchased a Hot-end and An extruder assembly (with heaters, etc). It looks like the mount for the hot-end is similar diameter to the one already on the extruder that is on the SD3 I have. And without disassembling the extruder on the printer I cant tell if the one i have will have matching mounting holes.

has anyone else done a similar thing? What I'm needing to know is are there any roadblocks to doing this from someone who has actually done it at some point?

My hot-end is longer than the one on there now (and heftier with much better insulation), but I assume that's not an issue since that's just a matter for correctly telling the software what the zero height will be with the new head on the machine.
