Mo' Cello parts for the O'cello

thingiverse

I customized and added parts to the O'cello after making my own. This is an extremely cool print to make, and it's not too hard to build with close attention to detail. update: I made a scroll for the top too. https://www.thingiverse.com/thing:2672095 One change I made was to use 12mm and 10mm hardened rod that I found on eBay for the neck and endpin. It is very sturdy. I also used 3/4" by 1/16" thick aluminum angle from my local hardware store for the knee bar, and it fits perfectly. Firstly, I made undrilled tuner STL and STP files of Part 6 from the O'cello. This will give you a head start on laying out fresh tuner holes to match your tuners. The STP file is reverse engineered from the original STL files, so some flat planes are not perfectly flat. It does not affect the build, but it's just something to look out for. I built my O'cello from them, so I know they work fine. Next, I added my Part 6 custom version that I made to fit my tuners. Sorry, I don't know what the tuners are - they have no name and have been sitting in a box for a few decades. They're small guitar-like tuners, not big bass tuners. You don't need huge tuners for cello strings. Also, my tuners don't need an extra plastic plug insert like the original. I simply made the holes the size of the screws and post, and they function and fit just fine. The next parts are remixed from the Zarlor "Add-ons" parts. Zarlor's revised neck-heel design has a flaw in it. The bolt lug is not Boolean unioned to the rest of the part - only grouped with it. This may cause printing errors, as it did with my slicer. I unified it and have uploaded the repaired part. I also like the chest and finger rest he designed, but for my needs, there's no real need for the finger rest, as it blocks easy access to higher notes. Not adding it makes for a very weak join to the neck. I cut down the long finger rest so that it is just the block needed to fill the joint. It is easily super glued in place. Make sure to check the orientation, as it only fits one way. Lastly, I made a simple hook that can be glued on to the side of the neck-heel part. This is a handy place to hang your bow when not in use.
