My wife wanted a Deathly Hallows symbol to hang on the wall to go along with my others, so here it is! This is HUGE and will not be able to print without scaling. I suggest scaling the entire thing down to the size of your print bed or whatever size you want it, then scale the Z back up to be at least a 3-4mm tall for maximum effect!
I will post my printed one that is just shy of 1' (300mm) tall.
3 top and bottom layers. You can do 2 for the backside, but supports will show through. 2 or 3 walls, doesn't matter.
I used a .6 nozzle even on this and it printed in about 2 hours.
