This is a cylinder that topples over itself and seems to roll! very addictive and very challenging!
you can increase the bottom/top layer thickness to put more mass into the ends making it harder or easier to balance. the best weight i found what 30g, play around with infill until you hit that. Your slicer should be able to tell you how much your model will weight. if your having problems with the slight overhang increase your wall thickness! enjoy!
check out the youtube video to see how i designed this and for in depth print settings!
