Double Spinner Post and Caps

thingiverse

Here is a twist on the spinner. Stack two spinners of any type within reason on one shaft, add some caps, and you have something different. Simple. Shaft and caps are laid out at 8mm. Caps snap on nicely when printed. You may need to add a drop of glue depending on your printer. The shaft must fit tightly into the bearing or the spinners will wobble and contact each other, so you may need to scale up or down depending on your printer and filament. I use a Prusa MK2 with .2 layers using BAM TACK filament. It works perfectly. I printed the caps without brim, and 2mm brim on the post. I designed and printed two spinners for this demo because I don't have any existing ones.
