Thanks a lot, Martin and Omar. I’m active again after 2 days — I needed a break because I was getting really stressed out. Every time I model, a new problem shows up, and tackling those was stressing me out so much that I rage-quit for 2 days.
I tried what you guys suggested: I started with a cube, duplicated it, and merged faces to form the two holes. But I still can’t figure out how to create the full shape I marked. Especially that specific part at the end where there’s a sharp section sticking out — I just can’t figure out how to make it. I don’t know what to do anymore, please help me.
