Dayton Motor Electrical Box Extension Lid

I made this for a booster pump that I was installing.  The electrical box that was on the pump was so small that it was impossible to wire it up, so I made this lid to give some extra space.  I think it will work with a variety of Dayton products like you would buy from Grainger or Zoro.

The pump that I used it for can be found here:

Dayton Pressure Booster Pump, 2 hp, 208 to 240/480V AC, 3 Phase, 1-1/2 in NPT Inlet Size, 3 Stage 45MW29 | Zoro

2 hp, 3 Phase, Booster Pump - 45MW29|45MW29 - Grainger

I made this model using Solidworks
