Spinning Witches Key FOB

thingiverse

Every Witch needs this key fob for their Broomstick keys, a fun talking point over the Halloween period that will also be appreciated by Witches all year round. Like most key fobs, this is purely a fun, decorative accessory. The design features a Witch on her Broomstick in the center of a rotating/spinning ring. The Witch and outer surfaces are raised so you can have fun making it in two colors by pausing your machine mid-print (twice) and swapping the filament - this is easy to do and creates a great result. The mid section starts at 2mm build height and is 1.5mm thick, so swap filament at approximately the following build heights: First color change: Change at 1.5-1.8mm completed (before the center section starts to build by bridging between the Witch and the outer rings). Second color change: Swap the filament back as soon as you see the Witch shape appearing above the center bridged surface, change at approximately 3.8-4.0mm completed. For members with a dual extruder machine, split files have been added for ease of printing the Witch fob in two colors. Part A will print the bottom 1.8mm and from 3.8mm to completion, while Part B will print the 2mm in between. This is a small (34mm diameter at standard scale), quick and easy print that uses very little filament (7gm with a Raft). They make great gifts and can be printed to suit any Witch's favorite colors. A well-sliced file printed on a precise/accurate machine should result in a fob with a center section that will rotate with minimal effort required to free it up. Running a fingernail or craft knife around the groove between the inner and outer parts (refer images) is all that should be required. Applying a light (silicone) lubricant in this area will help it rotate well. However, if your fob won't rotate and you can't free it up, you can scale it up uniformly (5-10%) to increase the designed-in clearances. Print one/some today to stay onside with the Witches in your household/life or risk having a spell cast upon you! (And please post images of your spinning Witch key fobs for other members to see.)
