Low poly Stanford bunny - refined, print optimized

I bet that all of you have already come in touch with famous Stanford bunny. 

Actually, for me, its low-poly version was the first print that I ever made back in a day in the university on an overpriced Makerbot machine that was just shit. Yeah, memories. 

BTW - did you know that Stanford bunny had a brother? 

Anyway, few years later I found it again digging through old files on my PC and decided that the bunny definitely deserves a refinement.

If you have ever printed original low-poly bunny (as I bet you have) then you probably noticed that the ears are slightly problematic, as well as some overhangs in the front. Some tri-faces also blend together visually to form quads, which I did not like. 

Since I do Rhino Grasshopper for a living, I stitched me together a little helper script and gave the mesh thorough cleanup, that includes the following:

1. Overhangs adjustment - all overhangs should be now printable just fine

2. Whole mesh was manually refined - relative angles of adjacent faces were maximized to pronounce reflections as much as possible and to prevent blending into quad-faces

3. Certain parts of the mesh were completely rebuilt. Eg. ears, left back leg, tail area...

I mean.. I actually modified the mesh so much that I considered not mentioning it is actually a remix, because there is hardly any vertice left untouched, but whatever. I had fun doing the rework because I turned it into a game :) Move vertices to minimize the amount of red edges, increase threshold, repeat. While also ensuring that bunny looks nice and overhangs are reasonable

I think that the result looks amazing and I also hope that you will think the same! 

Enjoy the bunny and have fun printing it.

PRINTING TIPS: 

Max overhang angle here is 60°. It works just fine with 0.15 layer height. Should you have problems when printing it, you probably have higher layer height. 

You can partially compensate that by increasing external perimeters width. I also recommend to increase it anyway. I personally went with 0.55 mm instead of default 0.45 (for external perimeter only)

Avoid placing the seams on the back of ears! Push it in between the ears instead using paint-on seams feature. I personally prefer to exclude edges until the slicer automatically grips the "correct" one. Paint- on enforcement, though faster, did not work that well for me since it sometimes makes the seams slightly misaligned. 

GCODE:

Attached Gcode has the seams carefully aligned as I prefer them, has the external perimeters width set to 0.55 and the print speeds quite low in order to minimize ringing. If you want it faster, you will have to make your own. Just don't forget to realign seams! :)

Bunny is approx. 75 mm tall
