Sandbox Part 6: Sandbox Design

Before I was going to be able to build anything, I was going to have to make a design. I did this in tinkercad, drawing inspiration from a few online tutorials. The design plan was as follows:

1) Sandbox area should be around 30 by 40 inches.
2) Projector and kinect must be elevated 40 inches.
3) Kinect must be centered over the sandbox.
4) Should be able to fit through most doorways.
5) Should be mobile.
6) Needs to be usable by people of all heights.
7) Needs to be strong enough to support 200 lbs of sand.

For the design, I planned to use a piece of plywood for the base, and 1 X 10 planks for the walls, projector mount, and structural support. To hold the plywood sheet up, and make it load bearing, 2 pieces of 1X10 were braced vertically under the bottom of the sandbox. Finally, 4X4 beams were used for the legs and projector boom, as well as one on the bottom to aid in the stability of the projector. The legs are placed on the narrow side of the sandbox to make it fit through doors better.
The projector would be mounted in a rectangular frame near the top of the boom, with the projector on the close side of the frame, and the kinect mounted on the outside of the frame, over the middle of the sandbox. The projector and boom assembly would be made removable by using large bolts with wingnuts to mount it. Finally, roller wheels would be mounted on the bottom of the legs.
With the design phase nearing completion, it was time to go and get the parts.
