Summary This is a remake of a desk toy I saw on ThinkGeek years ago ( OSM: Spatial Manipulation Toy http://www.thinkgeek.com/product/15dc/ ) . They no longer seem to sell it, so I thought I'd make my own. Enjoy. Clip together even numbers of the model (at least 6) to form a triangle or higher order polygons. Now you can rotate it in on itself by pushing the middle disks down while pulling the outer disks up. Print Settings Printer: Bukito Rafts: Yes Supports: Yes Resolution: .2 Notes: Supports aren't strictly needed, but it will help keeping the pins from drooping too much. I don't think you can get these prints to work without a raft, but you're welcome to try. I used 1.5mm wall thickness which negated infill for me. Adjust as needed.
