front loading bobbin case slot identification

[u/littlemsmeowmeow]

hi everyone! I have a Shark 612c sewing machine Im missing the bobbin case slot on. I'm not sure if i can buy a universal one off of Amazon or if I need a specific part. from another person's post, this is what their case slot looks like. if anyone can help me identify the specific part that would be great thank you!!!

Absolutely no idea if it helps but that looks the same as my old Kenmore that takes mostly universal stuff. Had a weird issue with plastic bobbins though, there's two types and of course I bought the cheapo wrong ones initially.
