Snowman Pin Walker

In the event snow is a no show...
I designed, 3D printed and assembled "Snowman Pin Walker" using components and assembly methods similar to my "Halloween Happy Ghost Pin Walker". Snowman Pin Walker is a snowman themed pin walker and, in comparison to the happy ghost, is quite large.
The center of mass for this model (as determined by Autodesk Fusion 360) is quite high, located at the fifth snowman "button" up from the base, at the center of the fore and aft / left and right extents of the model. In order to maintain side to side stability of the model, I designed the width, length and position of the feet on "Base.stl" for a N20 6VDC 100RPM motor operating at 3.7VDC. Motors with lower RPM ratings should work fine, but motors with higher RPM ratings, and / or operating the recommended motor at higher voltages, could induce side to side stability issues, or in other words, fall over.
I try to learn something new with each design I create, so in this model, prior to 3D printing the dual extrusion snowmen (I printed one in Tough PLA and one in PLA), I decided to enable the Cura 4.3.0 "Prime Tower" and "Ooze Shield" options to see how well these options improved the dual extrusion print quality. The time required to print the snowmen with these options enabled was around twelve hours each thus they easily qualified for "overnight" prints, but as shown in the next day photographs and videos of the snowmen, they came out of their ooze shields with no other clean up and with quite impressive results!
And as usual, I probably forgot a file or two or who knows what else, so if you have any questions, please do not hesitate to ask as I do make plenty of mistakes.
Designed using Autodesk Fusion 360, sliced using Cura 4.3.0, and printed in PLA on an Ultimaker 2+ Extended and an Ultimaker S5, and in Tough PLA on and Ultimaker 3+ Extended.
One final note, I receive no compensation in any form whatsoever for the design, equipment, purchased components and/or materials used in this model.
