Filament carrier base plate for German Reprap Neo - fortified

In the original design ( http://www.thingiverse.com/thing:624871 ) the hook broke at the base plate where it is put into the hole of the printer. I therefore added some extra strength to this piece. For the spool holder itself I modified the part being provided to fit my filament spool.

I printed this without support, as I cut off the hook accidentally when removing the support parts (it was in the original design though where the hook is not as strong as in the modified version).
