Hello, 

Hello everyone, i am new to cad programs and new to solidworks as well. I am learning from videos on youtube and practicing on my own with projects i want to 3D print. I want to remake a handle for my soldering iron because this one melted and deformed the plastic and it doesnt fit together nicely anymore.I managed to model this handle like i drawed it by hand on this picture with shelling and all but i cant figure out how to make a small round stop on the inside. This feature is ment to stop the plastic that slides in going too far down. I added it in my sketch but i cant edit it afterwards or i just dont know how. 

Can someone please help me and tell me how can i solve this problem. 

Thank you
