Fixed up the non manifold triangles in this Marvin remix, I added custom supports to print better, accidentally fused his head stick support with the head, but that's easy enough to snip off.
Two files, Marvin with support and without in case you want to set up your own.
I've printed 3 of these with custom supports up to 60mm/s speed and no failures yet!

Notes:
Model with supports built in needs no additional, model without the trees will need a lot of supports and have not tested with auto generated slicer supports.
