Oh and like you said, making the propellers in opposite direction too...I wonder what will happen if I use the air pump to make it go like in my video, but instead of spinning it might just lift up?! :P
Thanks for that! I shall give it another try when I have time to draft up the CAD model. I'm thinking having 6 props and alternating the air duct directions. See how it goes! :D
You're problem is the torque imparted from all the propellers spinning in the same direction. The torque from each of them sum up to make one large torquing moment. Multicopters overcome torque by making every other propeller turn in the opposite direction, which would mean youd need an even number of props (4 or 6). I wonder if that would solve your problem.

Spin top.stl - printing everything in one go. The propellers will have supports underneath, which will need to be removed and then re-attached to make them spin. The 5 caps are to be glued to the spigots to hold the propellers in place. The ball is to be glued to block the hole at the bottom of the object.
Spin top (body).stl - the main body only.
Spin top (propellers and bits only).stl - the propellers and small parts are separated from the main body so there's not as much supports required as in the whole set.
