From the Take a Break Tuesday Destress and Focus Hackathon, 13 Dec 2022

Materials:

• hot glue, epoxy, or superglue
• qty 16 5/16″ hex nuts (or possibly 3/4″)
• qty 1 skateboard or inline skate bearing

How to do it:

• Connect pairs of hex nuts together along an edge
• Connect pairs of pairs together one edge away from the bottom of each stack, in a “V” shape
• Glue the sets of four nuts together around the skate bearing, filling in the gap with glue.

Tips:

Don’t connect more than two of the inner circle of nuts together first if you are using 5/16” nuts; they will not quite fill the circle and it will be too small for the skate bearing

If you have issues with glue alignment, don’t be afraid to peel off all the glue (especially if you are using hot glue!) and do it again.  *However*, know that if you peel off some of the hot glue, you may have to remove any connected pieces of hot glue, as they’ll be loosened.
