Pipe covers

i designed the first draft for the second pipe “cover” as there is two, with this pipe i decided too go for a different approach and have the “cover” go on the inside instead of covering it form the outside

I learned about custom features in onshape. and discovered the fill pattern feature. which basically fills a object within boundaries with what ever shape/ hole you want. this proved very useful. in insuring that the air can flow naturally. i also tested the first design for a fit and it was perfect. i am now printing V2

I built the first version of my design some of my worries are that there might not be enough holes and the pla i am 3d printing these out of might warp in the heat
