+// With this spool you can re-spool thread from bigger spools, which have too much 
+// mass and tend to cut off or break your needle. Unfortunately its not fully automatic, 
+// because you have to use your fingers to guide the tread while respooling, to make
+// sure, that the spool is evenly filled, because the respooler is originally designed 
+// to spool the under-thread-spool and therefore not suitable to respool a large amount 
+// of thread nor spools of this height.
