Someone pointed out that the heat set inserts I was originally using were thicker than the ones I linked to in my parts list.  The place I got my inserts from is a local seller in the US and the are not consistent with there stock so I decided to remix my parts to match the AliExpress inserts.  I moved the original parts into an 'insert large.zip' file and now the base parts should be sized right for the aliexpress inserts.  I also updated my parts list to fully specify what insert to buy.

I'm sorry if you already printed the parts, hopefully it is not too much trouble to reprint.
