Wheel of Whatever (WOW)

The intent of this model was to provide a flexible roulette wheel design which can be use to empower your ideas, just let the end use guide your choices.   The Wheel of Whatever (WOW) has been designed using magnets which are imbedded into the fly wheel and in the message plates.  Simply slide the message tags into the fly wheel and connect the pre and post messages.  Then spin the wheel.  To remove the messages from the fly wheel an ejection pin has been created to fit into a hole on the back of the rear panel.  Once your done using the ejection pin it can be stored away in its cubby located on the side of the panel.

For me, I plan to use it to help my team make a decisive decide on what type of food we should have for our Friday lunches.  However the project is not limited to food only selections, using the OpenScad files provided you can tailor your own messages and themes in just a few minutes.   See the Automation section for more details.

Lastly, I wanted to add a place to store the messages and tags I created, so I added a little storage drawer just for fun.

Warning: The first time I put this together I got a bit crazy with the magnets.  This was a mistake in short the wheel would not spin.  On my second attempt, I took a more pragmatic approach and only added a few magnets to the rear panel then tested how well it spun and indexed.  My final result ended up using 4 x  5mm  Dia.  x 2.75mm neodymium magnets.  As shown in the image provided.  3 were used to attract the magnets an one was used to repel the magnet.  Depending on the strength of yours you could need more or less.

Printer and Printer Settings:

Printer: Ender 3 v2

Material: PLA

Layer Height: 2.0

Supports: As little as possible. For the lager prints I included a mask to help adhere the print to the build plate, however you may not need to do this.

Important Printing Notes:

• Spinner Panel Front:  Requires supports for the 5mm lip at the bottom of the piece.  The remainder of the part should not have any supports printed and must be blocked.  Using my slicer application I created a pause at layer 30 using a post processing command. This pause is required, as it allows for the insertion of the Pre-Message Insert, Post-Message insert and the Spin-Now insert.  Remember to add the magnets into the pre and post message inserts prior to continuing the print. See Images for reference.
• Each of the inserts where printed with a brim, then I trimmed the brim leaving some of it to help secure the inserts during the print.
