Singer 301

I recently picked this machine up from a thrift store I like to frequent for 75 dollars! I thought it was quite the steal - I’ve been sewing with it the last few days and it’s been a dream. It’s so quiet, so fast, and just overall I’ve had a great time. Compared to my featherweight and singer 66 treadle it’s a great middle ground machine for me. I fear I may have messed up though… this machine came with an absolute load of attachments one in particular being the zigzag attachment. I was testing it out for a while and went to replace the bobbin and absolutely snapped the little arm on the case 😭 I guess I’m seeking advice on what to do next. I’ve heard they share the same bobbin cases as the featherweight, but I’m honestly worried about breaking it and ending up needing two cases. Is it worth spending the 80 plus on a supposed official 301 bobbin case or is there something else I could do??
