A castle topper to show off your mathematical prowess while molding the sands!
Based off of a 3D projection of the equation Z = sin(sqrt(x^2+y^2))/sqrt(x^2+y^2), simply pack the mold with wet sand and add it to your castle for an awesome accent!
When I saw this challenge I knew I wanted to create an interactive and interesting way to view mathematics in the 3rd dimension, having it look really awesome is just a plus!
To make this model I used blender 3D modeling software, subdivided a plane into ~65k vertices and set each vertex to where it would be when plugged into the formula. From there all I did was create the mold around the function.
Unfortunately where I live I didn't have access to any sand to mold so I used brown sugar instead.
Edit: Added a solid version for those who just want a neat model of the function.
Edit (7/31/15): Made and uploaded a much cleaner and useful version, it prints without support and allows a cleaner sand mold, plus this one actually works in slic3r.
Edit(7/14/15): Made a version with the function on the side.
No supports needed! Just print pack and play!
The base model is 10cm x 10cm x 4cm, use that to scale it to any size you want
