AutoCAD 3D Rendering of Longboard Frame

3D rendering in AutoCAD of the frame of my longboard. Overall length is 40.5", the length of the square tubing frame is 26" by 9" using 3/4" aluminum tubing that is 1/8" thick. End pieces are 1/4" thick aluminum. 1/8" thick aluminum plate will be used on the top on bottom to the board. Aluminum was used to keep weight down.

 All the batteries and electronics will go in the middle, I'll make battery packs out of 60 used Samsung 18650 batteries that come out of laptops. Which should fit nicely because they are just under 3/4" diameter. Modifications will have to be made to the motor controllers to make them fit. I may also include a few chargers so I can just plug in a power adapter to charge it. But more on that later.
