Enjoyable to use in your hands, and strong enough to even toss around.\u003c\/p\u003e\u003cfigure class=\"image\"\u003e\u003cimg src=\"https:\/\/makerworld.bblmw.com\/makerworld\/model\/DSM00000000555152\/design\/2024-07-24_8vfjup8xaszt.gif\"\u003e\u003c\/figure\u003e\u003cp\u003eAll parts are designed so that they can be printed without supports or brim, and you'll need to print \u003cstrong\u003e60\u003c\/strong\u003e arms, \u003cstrong\u003e20\u003c\/strong\u003e three-way connectors, and \u003cstrong\u003e12\u003c\/strong\u003e five-way connectors to assemble. The version shown in the pictures uses the 6 cm arms, which creates an expanded shape around 25 cm.

Importantly make sure that the five-way connector is facing in the opposite direction as the three-way connectors (i.e. if the smooth side of the three-way connectors are facing down, then the smooth side of the five-way connector should be facing up).\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003eIf you did it correctly, the full set of 15 arms should be able to fold together like is shown in the second picture below.\u003c\/p\u003e\u003cfigure class=\"image\"\u003e\u003cimg src=\"https:\/\/makerworld.bblmw.com\/makerworld\/model\/DSM00000000555152\/design\/2024-07-24_stg9pl9dp33h.jpg\"\u003e\u003c\/figure\u003e\u003cfigure class=\"image\"\u003e\u003cimg src=\"https:\/\/makerworld.bblmw.com\/makerworld\/model\/DSM00000000555152\/design\/2024-07-24_r3hyj3ifcdhz.jpg\"\u003e\u003c\/figure\u003e\u003cp\u003e#4: Now the fun part! Work around the ball linking in the remaining three-way sets using the five-way connectors (making sure that the smooth-side of the five-way connectors are always facing towards the center of the ball). Although it may at first look complicated, really you're just creating a bunch of triangles - and so you'll find there's only one obvious way to join together each five-way joint.\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003eI did the assembly with just my two hands, but it certainly may be easier if you can recruit a second set.
