Contact haydn.huntley@gmail.com for MagBalls, magnets, and extremely carefully assembled, precisely measured carbon fiber arms.
I test and measure each set of arms. The magnets in the joints will have a measured holding strength on a ball stud of at least 1.5kg. The arms in a set will match lengths within 30µ, according to my calipers.
Note: All sets of arms include MagBalls, N52 magnets and CNC'd Delrin ends.

Here are typical measurements for the new high-precision MagBalls:

These are about 10x as precise as the previous ones I was able to have made.
