Dovetail Puzzle V1.1

11.8.18 Update: added a new version with slots for the magnets
i have a 8mm diameter metall ball and two 8mm diameter (1mm hight) neodym magnet
I put the magnets in the slots and close the slots with a 3d pen with the same filament, but i think you can use glue too
I changed the hole on the close-side (shorter hole) so that the ball sits perfect there.
I changed the dovetail slightly, so that it moves even better.
