Singer Replacement Spool Retaining Ring

I'll give this design a shot since it's a starting point! My wife asked me to create an adapter for her two sewing machines, and she really wanted something small so it wouldn't get misplaced. I'm glad that printing extras will now be possible. This could also come in handy for other users of sewing machines who might want duplicates on hand. If the adapter is too loose when printed, you can try heating it up with a flame from a lighter to tighten it before inserting the four holders. Alternatively, you could scale down the file by 2-3% and print another one to achieve the desired fit.
