Soda Bottle / Pipe Coupler for POV Baton

thingiverse

This is based on the Genesis Poi project. https://www.thingiverse.com/thing:918847 Can also be used to couple bottles with pipes for fluid projects! Got tired of poi and wanted to try baton instead. A secret advantage is that an extra battery can be hidden inside the pipe, or even extra electronics to provide fancier or larger pattern sets, not to mention controls. EDIT 11/19/2017: After trying to twirl with 1/2" PVC for the first time and failing miserably, I looked up the standard diameter of a baton (which I should have done initially), which is 3/8ths. 3/8ths PVC is way too flexible, and too thin to fit any electronics inside. Revision-wise, I added a hexagon option to prevent the baton from rolling away when dropped, and lengthened the threading area for better grip. Modified from MrWhat's SCAD file after eliminating unrelated clutter.
