Here is another cool gift idea for gearheads in your life. The Wankel Rotary Engine Fidget Spinner is CNC cut from a full piece of metal. It has a stainless steel and brass construction. It measures only 4cm, so you can easily fit it in your pocket and take it with you anywhere. You can simply rotate it with your fingers to relax and take your mind off things.
