Shipping Crate for Speaker

grabcad

I needed to ship a pair of vintage Altec 9846-A Compact Studio Monitor Speakers.The "compact" part is pretty funny, as each cabinet is roughly 24" x 20" x 15" and weighs 74 pounds.I thought I was going to use a pallet and freight shipping, but it turns out FedEx will accept packages weighing up to 150 pounds for ground delivery.The crates are away. Each empty crate weighs about 16 pounds. It is pretty impressive that such a light frame will transport 70 pounds of gear.The frame was made from furring strips (only $1.60 per 8 feet). Padding foam came in the form of Pool Noodles (only $0.25 since summer is over!). The plywood was taken from another crate in our shipping department. To hold everything together I used lath screws. They have a great button head, so the wood will not split like it would if using a flat head screw.All I needed was a crate to insure safe delivery. This is my design.I surrounded each speaker with pool noodles, as they were the cheapest foam option I could come up with.One speaker per crate.Photos of the real crates are attached. Obviously the rendering look better. No need to deal with warped parts, or out of square corners with the CAD data :)While contemplating how to build a crate, I found these two great resources.
