I am trying to create a new insert/cover for this medical device. I watched your video (YouTube ID: 7F2SkJhI2g0) and followed along as best I can but I just can't seem to get the shape I need. Basically, this insert would need to go inside a 1mm cavity with cutouts for four 10mm buttons, one rotary encoder/wheel as well as it's symbol. I have been at this for weeks trying every method I can think of but I just can't get there and could use some help. Right now, I have two big bumps where it should be flat. There's a 3mm rake along the 90mm length of the insert. There's also curves upon curves which I believe is where I'm getting tripped up. I feel like I'm close but there's just something I'm missing.
Any help would be appreciated!
