Electric Cord Pass-thru Flange Assembly

grabcad

I created a flange assembly to pass an average 5/16-inch power cord through a 1/2-inch plywood barrier. I have a chicken coop that I run a power cord for lights and a water heater. The power cord runs from a room outlet through a plywood barrier to the chicken coop. The tolerance between the plug and the inner wall of the flange is 5/100ths of an inch, which allows for a friction fit. The model was created in FreeCAD Version 0.20.2, and it was printed on a Creality Ender 5 Pro. I printed the part with 20% infill and 5 layers sidewall thickness. This gave the parts very good rigidity.
