250g spool adaptor adaptor

This is and insert/add on to another specific 250g spool adaptor to work with the specific iSANMATE spools I had. I had downloaded and printed this model that would not grip my spool at all, making it unsuitable for my instance. Instead of throwing out what I had printed I created a small additional insert that fits compltely snuggly both on the model and the spools I was using. This profile prints on my X1 great with NO SUPPORTS. There is some bridging required that works out despite the curve.
