Center of Gravity (COG) finder for RC planes

thingiverse

This tools helps you find the center of gravity for your radio controlled airplane. It uses pencils with erasers to avoid damaging the wings. The bases have a 9/16" opening that holds a nut for added weight and stability. The parts are sized exactly and will snap together if you get your print settings right, but you'll want to glue them. On and Ender 3 pro with eSUN PLA+, setting horizontal expansion to -.15 worked perfectly, but you'll have to experiment with your own setup. You may also need to scale the collars up or down to accommodate your pencils. Everything prints without supports. Print the connector right side up and the rest upside down.
