I had some trouble getting the fins to stick at first until I added a brim. And I accidentally broke a tooth (the model, not mine!) pulling the support out of his mouth. But other than that it turned out pretty nice! Best of all, my a splatoon-obsessed wife loves it!
I scaled it up to ~40% and printed it at .175 layer height on my MP Select Mini. I think I'll order some gold PLA soon and try a finer print.
Great job on the model! Thanks!
