I used the original design from Intentional3D, made my own, but disliked the knob design. So, I reworked the shape of the knob in SolidWorks. I also reworked a few things to make the model bow less when printing. Also, i added extra caps in the rods closest to the knob, because they came out when I was playing with mine.
Print at a medium speed. Does not print well in Ninjaflex or similar materials
How it Was Edited
I edited the model by using SolidWorks and the original part file provided by Intentional3D.
