Spot the mistake

Can you see what's wrong in this picture?

If you said "those spindle arms are way too long" you're right! They are so long, in fact, that they bump into things on the back of the replicator and don't spin Friggin all day print and I wasted so much time printing those parts too long. So did I reprint new arms? Heck no. I just cut them shorter then fiddled with things until it worked. And now...

It's good to go. Of course I fixed the source files that I uploaded to thingiverse so no one else needs to modify it after printing. I really should tweak it more and make the arms even shorter, but I just can't be bothered with it right now. Plus I kinda like keeping the ends standard so that one day I could use this monster.

P.S. Tried out yet another whistle. Still not as good as the champion.
