This funnel has been designed using RS DesignSpark mechanical 4.0. The purpose is to facilitate oil to be transferred to the generator without the need for any other equipment such as pipe due to the limited space. Using DesignSpark Mechanical 4.0 new feature - Blend tool. If you do not wish to use the funnel it is still worth the while to explore the new feature available in DesigSpark Mechanical 4.0 I have included an alternative design with the tip set at an angle.
