This is my overly complicated solution to a non existent problem. My local bar has twelve beer taps, so I designed a wheel of fortune for people who are not sure what they want to have.
You can read more about this over at my blog - http://mavrodinov.me/improving-ux-through-rng/.
I printed the wheel solid. You can get away with very little infill for the other parts.
You'll need to print the bolt cover model twice. Everything else just once.
- I cut a piece of 2x3 cm wooden profile to form an upside down T stand
- a generic skateboard bearing should fit in the center of the wheel. Depending on print settings and tolerances, you might need to sand the hole a bit
- I used twelve 3mm bolts with washes on both sides and matching 3mm nuts. Once all bolts have been placed and tightened, place the bolt covers over them and tighten them by hand
- the wheel connects to the holder with a small piece of 8mm aluminum pipe.
- indicator_arrow and holder.stl parts both have holes in the back. They should fit 3mm screws to secure both pieces to the wooden frame
- indicator_arrow has a small slit in the middle. Fold a piece of paper and slot it inside. It's used to slow the wheel down, so it doesn't spin too fast
- finally, put the pipe topper and tighten it against the wheel
