Randomly picked and studied a putative protein: UniRef90_A0A359H533 AKA "Carl." I was watching a lot of Walking Dead at the time...
Here is the link for the amino acid sequence:
Using a bunch of other software (Uniport, Swiss-Model, Chimera, MeshLab) I was able to turn the amino acid sequence into a 3D model and figure out some cool properties with the protein. Feel free to message me if you want to learn how to do this!
I definitely recommend supports if printing the model in one process. You might consider slicing and printing the model in sections then gluing the parts together if you don't want to use supports. With supports, there was a lot of cleaning up and smoothing needed in all of the crevices. Also, consider rotating the model in your 3D printer's software to optimize a better print time and reduce the amount of supports needed.
Try printing the protein in ABS and do an acetone post-process for a nice finish!
Additionally, I significantly reduced the polygons in the model. There were tens of thousands of polygons in the original model so I reduced it down to approximately 7,500 polygons.
I plan on making this into an educational model to teach those interested in taking an amino acid sequence and turning it into 3D models. Helped me understand more about the protein when I was able to hold a 3D model.
