About this 3D model

a simple cylinder fitting the 15x3 countersunk magnet for aerostock effector. This cylinder is itself countersunk so that is is easy to screw on a piece on wood. To buid the rods, - drill the 12mm steel balls, - approximately cut the 4mm carbon rod, - CA glue one ball on one end of each rod - put a drop of CA on the other end insert the ball and quickly set all this on the two magnets to adjust the length That is ! For those who like, here is a video of the piece being printed with aerostock and its magnetic effector : http://youtu.be/pEInkU6yrcI
