Two-Arm Fidget Spinner
Fidget Spinners are very common but most kids want them now. Except they are hard to make but not really.
You'll need:
1. Hot Glue gun + Glue
2. 2 Nuts 19 mm
3. 607 bearing
4. Rubber bands
The First Nut
For Step 1 glue the nut onto the bearing edge. Now Glue the crevice pointed out in the image and do the same on the other side.
Copy to the Bottom Side
Repeat Step 1 on the opposite side of the bearing.
Add the Rubber Band
Add a decently sized rubber band that is strong. Mine is a little large so I had to double it around, that is the most you'll wanna do. Now glue it down where you need to.
Tips
Use cold water to cool the glue then dry it.
Use wide small rubber bands.
Grind rough edges were you are gonna glue to metal.
Buy 607 bearing if possible.
Finally, No other glue works as well as hot glue.
