Rolling/Flip Stick

I've designed and printed these wooden objects myself after seeing them. There were several design changes, about 10 in total, before finding this setup that works best in terms of shape and weight. A new version using M8 nuts instead of bolts is available at http://www.thingiverse.com/thing:2214933. Best results include printing end caps solid with 100% infill using a flexible filament - regular filaments can also be used, but a soft pad will need to be added after printing. The center part should be printed in any plastic desired, with at least 4 shells and 4-6 top-bottom layers, all with zero infill. This can be seen demonstrated in https://youtu.be/bEN3cazvPQU. End caps are pre-threaded for M5 bolts to add weight. A "CapWithBridging" file has been added, which is a thin single layer membrane placed where the M5's head stops and the threaded area starts. This allows the printer to bridge the gap instead of creating hair-like messes typically seen with flexible filaments.
