Shipping Container Cable Gland

I wanted to put a dehumidifier inside my shipping container, and allow an electrical extension cord and water hose to pass through to provide power to the dehumidifier and allow exhaust water out without rain leaking into the shipping container.

The original CAD is available via onshape: Shipping Container Cable Gland. I highly recommend copying the CAD, editing it for the exact dimensions of your hole and cable, and printing your edited version.

Instructions:

• Drill a 2-inch hole in the metal wall of your shipping container. I used a carbide grit hole saw, and it took a while.
• Measure your resulting hole and update the construction circle in the “Plug & Holes” sketch - mine came out to 2.024 inch. You want the plug to be a snug fit in your hole.
• Measure the cables to go through and edit the sizes of the holes in the “Plug & Holes” sketch.
• Print “Plug” and “Plug Insert” in TPU. I used Overture 95A TPU, but pretty much any TPU should work. I recommend printing them separately to avoid too much stringing between the parts.
• Print “Nut” in something hard - I used PLA.
• Put extension cord plug and hose through the nut inside the shipping container, then through the hole. The less beveled side of the nut should be facing the wall of the shipping container.
• Press cord and hose into grooves in “Plug”.
• Slide “Plug Insert” into the plug.
• Push the assembled plug into the hole in the shipping container.
• Screw the nut onto the back of the plug. Hold onto the ear that sticks out if necessary to keep the plug from pushing out or spinning.
