Nắp che giắc cắm rơ moóc 7 chân

I made this to cover my 7-pin trailer plug to protect it from rain/snow. It's probably not totally waterproof, but it goes a long way to keeping the moisture out. It has a nice tight fit with the standard 7-pin trailer plug.

Print instruction:

• Use PLA or PETG
• Print as oriented in 3mf file. 
• Only use small amount of support on inside so you can easily remove them. 
• Increase top layers to 7 or more to provide additional water protection. You don't want any gaps between the layers so good extrusion is essential.
