magnetic prop balancer
thingiverse
This balancer balances up to 10-inch props with two powerful 10x3mm disc magnets holding it steady in place. CAD files are available for you to customize and modify to suit your needs, whether you're looking to replace the existing magnets or adjust the gap between the arms to fit your specific balancer perfectly. The gap is a precise 68mm, but can be easily increased by sliding the arms into the channel until it fits snugly in place. Leave just a tiny gap on one side of the balancer rod so that it hovers barely above the surface.
