Awesome set! I just wanted to point out for the snowflake-cookiecutter.stl one of the internal loops has effectively no material, so is not fully connected in the print.The gingerbread's cuff waves are also too thin and end up not fully connected after slicing (edited)
Great model! I scaled it to ~77.6%. This way, the marked lines actually (somewhat) match a centimeter scale. And I think it still resembles the size of a (small) banana. (edited)
A good print! It's helpful for showing scale in a picture. I included another banana print for scale! Both seem to do the job well, though this one has lines to measure. Off hand, I'm not sure how accurate they are to inch lines, but it should be close enough!
I have an Ender 3 so I needed to crop the sides of to fit my print bed. Otherwise it came out great and my coworker that teaches chemistry was super excited for these.
