This wee model is simple puzzle I designed and made. The objective is to spin the five rings around to the right orientation with the use of the four different symbols on the rings. Once you think you have the correct orientation you put the ball in the top and hope it rolls out the side, but if it's wrong it wall fall out the bottom! This model is split up for printing, and puting it together is pretty self explanatory. Only bits that need fixing together is the Top and main body (however you could try printing it all in one and hope the rings run fine) With the ball, you can print that one but it would probably be easier to use a small ball bearing ball or a marble :)
