When one has a 3D printer, and one has children and grandchildren of a certain age, there are certain fundamental laws that must be obeyed.
You will be asked to print Pokemon.
I faithfully followed the directive, finding a suitable Pikachu model on Thingiverse and printing it in a brand new flexible filament purchased for this very task. But it turned out the tail was not up to the heavy duty required for toddler usage.
So I remixed the design and added a small strengthening part to help prevent the tail from detaching.
This is, by far, the most popular upload I have made to Thingiverse, and is also by far the simplest.
My amazingly complex contribution!
