I followed the priming and sanding section of BrittLiv's Instuctable on How to smooth PLA.

Many hours latter it was time to put everything together. With the stl files it was time to get printing. Now that I had one happy print ready horn design I duplicated and mirrored it to make the other horn. Using Fusion360 I split the model into two halves and added a peg so I could make sure I lined them up properly when I was gluing the two halves together. Sadly I dream bigger than my 3d printer but not to worry that is what super glue is for. Then using the revolve and offset commands I made a series of evenly spaced holes around the base of the horn. To make the sewing work I placed a hole in the base of the horn. I was going to be attaching these horns to fabric and the easiest way I could think of was to sew them on. Now that my horn was editable it was time to get to work. Again I turned to an article on Autodesk's website.

Now that my awesome horn mesh was in Fusion360 I had to change it to a BRep to make it editable. Once I had my 3d model looking the way I wanted it was time to import it into Autodesk's Fusion360 program.

On the bright side that means that this is an achievable beginner project because I am a beginner! The tip I will share is that I found starting with an imported plane worked best for me. I'm not going to go into detail on the sculpting process because I pretty much just read this article by Autodesk and smashed my head into my screen until I was happy with the way the horn looked. Meshmixer is a program by Autodesk that lets you mash up meshes as well as sculpt in the 3d space. If you just want to skip to the printing I am including the STL files I created for printing. After looking at a lot of Beefalo pictures and my Beefalo plushies it was time to dive into Meshmixer.
