The idea of building a 3D Printed enclosure for 2 pin plug was came into reality when the one of the 2 pin plug enclosure got broken and I had no other to replace at that instant.This repair will benefit for anyone who experience similar situation like me.The part was designed in "Tinkercad" and printed on Cube Pro Trio .Designing a custom plug in Tinkercad was very easy because it is easy to use and you don't need any previous knowledge to start design any model.I have chosen dimensions based on my requirements . You may choose it based on your requirements.
