JG Aurora A3 Spool Holder Extender

I used the JG Aurora A3 Spool Holder for several spools without problems. Unfortunately the latest ones are a bit wider and do not fit. Therefore I made an extension to the spool holder.

If you read this before you print the original spool holder, maybe you better use it and redesign it to be longer (and stronger in that case!). My extension is not very beautiful, but it works.
