Rotating Key Chain / Fob... with spinning MakerBot Logo!

thingiverse

Every Replicator owner / user needs one of these on their key chain. This key fob has an outer, middle, and inner ring that spin freely and independently from each other. It is a great little thing to show what is possible, a real conversation starter that goes wherever you go. Easy print with designed-in support... on a Replicator 2 the support comes away easily and cleanly, leaving the middle and inner rings to spin freely. A quick spray with some silicone lubricant (non-greasy and dry finish) makes it spin really well, like a bearing. To make it multi-colored, change the filament at 2mm and again at 6mm when using Raft (approximately 1mm thick). If not using Raft then change it at 1mm and 5mm. On a Replicator 2, this prints best at high resolution (0.10mm) with Raft on, five shells, and 50% fill to make it almost solid and strong. It doesn't use much filament because it's small. The designed-in support breaks away easily from a well-set-up machine, leaving the middle and inner rings to spin freely... but a quick spray of silicone lubricant makes it spin even better. To make it multi-colored, change the filament at 2mm and again at 6mm when using Raft (approximately 1mm thick). If not using Raft then change it at 1mm and 5mm.
