Fixes for Ferguson's Mechanical Paradox Replica Thingiverse #93418

The attached files are replacement top, bottom and connection pieces for the project described below.
I've been spending time with various gear design and testing and came upon the Ferguson's Mechanical Paradox Replica by sawdusty posted May 24, 2013. He stated that he had not printed the design and that he didn't know if it would work. The project was appealing, so I decided to try making it. I printed the parts as shown in the photos and found several issues:
1) The size of the holes for the pointers in the gear shafts are too small to print. I used CuraEngine with 0.35 nozzle and the holes did not print; in addition, the pins on the pointers are very fragile;
2) The pointers don't nest together with sufficient clearance for interference free movement anyway;
3) The shafts on the base for the gears are too large for the gears to insert;
4) The holes for the attachments are not present in the base plates;
5) The attachment pins are too brittle to work anyway (I printed with ABS) given the way the pins are printed -- they may work if you place them on their sides and then are able to clean off the supports without breaking the pins;
6) Slic3r did not like the gears. At all. It would crash when running under MatterControl every time. I used CuraEngine and was successful. Initial printing was done using an 0.5 mm nozzle; the gears printed with significant "waisting", dishing in toward the middle of the gear along one quadrant of the printout, making gear meshing difficult. That waist effect was significantly reduced with the 0.35 nozzle. Not having access to the design files, no attempt was made to modify the gears.
The attached files fix the shaft, pin, and attachment problem -- I did not address the pointer problem, but as shown, one can demonstrate the principle by using a Sharpie on the shafts.
