Love the model. It takes almost three hours to print one. I am new to this hobby, but you have a white outline. Why not make the majority of the middle layers in white, would save a lot of time in print. Maybe even bring the print to around 30-45 minutes.
I usually fill the bed and set it to print overnight, so I wasn't focused on speed, but you have a point. I created this a few months ago when I was just learning cad and honestly barely had the skills to do what I did, lol. Now that I'm getting a little better, I'll look into speeding them up. Thanks for the suggestion.
