Parametric CG balancer.
Designed to use removable chopsticks for transport.
10 minutes design... simple and fast to print.
Extended version uses 2 pairs of chopsticks, toothpicks and 2 rilsan necklace to instantly match a leading/trailing edge.
Measurement precision is really good.
Works by default for small or medium weighted glider/plane with chopsticks (works for all my gliders/plane even 2.7m)
You can tweak the scale and hole diameter variables to make it fit bigger planes and use bigger sticks.
