Wobbler with a sphere & TETRAHEMICON

thingiverse

This makes two halves that you then stick together to make one Wobbler. Turn the tubular rockers 90 degrees. Print two so you can play an eye/hand coordination game that fits perfectly in your hands. The goal of the game is to cross paths back and forth with each path crossing at about 90 degrees. It's actually pretty easy once you master aiming one to move left and right while the other moves towards you and away from you. I dropped them in the video and they happened to be crossing at about 90 degrees. The game in the video is called Accessum Centrum, which is Latin for "Toward Center," although Intersection might be a better name. I've found that a small cork board with a wood frame from Walmart works best because it offers good traction, is smooth and lightweight. The wood frame keeps the pieces from rolling off the edge. United States Patent 4,257,605 Bancroft March 24, 1981 "The rollable device of this invention can be used as an amusement device or as a game piece for rolling on the surface of a flat game board. As an example of using the device as a game piece, a player holds a flat game board with two rollable devices positioned so that when rolled directly across the board, they will cross perpendicular to the path of the other rollable device. The player who can roll the devices alternately across the path of the other rollable device the most times in a given time period is the winner."
