Hey Everyone!

I am trying to make this part and its not working. I have attached an STL of what I am trying to recreate. I have tried using sweeps, sweeps with guided curves and honestly im a bit dumbfounded at the moment on how to do this. Can anyone help please

Help is appreciated! thanks

Here's my update to your model that you attached. Hopefully some of the items can be adjusted based on your dimensions you provided. I left your data and added my approach to your file. I changed it so the transition between surfaces would be a bit more adjustable.
