O'Cello Part 6 Modification

Minor modification to Part 6 to give a better fit for the tuners. The original holes are too large and the wall is too thick for proper installation of the tuners (IMHO).

I purchased these tuners as the instructions link is not listing anything for sale now. They appear to be the same tuner used:

UPDATE AUG 12: I found that the thinning of the walls I had previously done was just a little too much. I have restored the walls to 15mm thickness.
