Another Berry Tripper

This is a remix from Berry Tripper. Basically parts I used from http://www.thingiverse.com/thing:86631 to make what I have shown.
I am using "MW_LargeHerringBoneFinal_Plugged.stl" to print the large Herringbone gear with the correct M5 nut size as shown in the photo gallery. A SKP file is also provided which is an STL import of the original file but with modifications. Obsolete files will not be removed but don't use them unless you want to.
**OBSOLETE** I had trouble printing the large herringbone gear to fit a M5 screw. It looks OK but when printed, it would fit a M8 bolt instead. So to work around this, a 8MM OD 5MM ID spacer was inserted into the center and a nut retainer sized for M5 hex nut was created to make it all work together. **OBSOLETE**
This is just one possibility out of the many options out there. This happened to be my take on it though I hope this can be of some use to someone else...
See instructions for details.
