Spin the coaster to decide who has to pay the bill.

Several versions are included:

• Wo is next
• Truth or dare
• Spin the coaster

Prints easy & is ready to go

It is print-in-place, no support material is required. No assembly needed after printing!

Customization

To customize it with your own text, please install OpenSCAD on your own computer and follow the customizing instructions on this thing page.

If you could take a picture of an actual print, please "comment" and attach the picture. - I am curious to see your uses in the wild!

Here is a video of the coaster in action:

Credits

I used code from this gear bearing from emmett to create the herringbone gear bearing.

Design

I created several versions until the coaster was spinning well. Turns out, both the gears (ball bearing alternative) and a heavier outer ring were needed.
