these buoys were the first ones I ever designed, and I thought I should share them so you have more of a simple and larger design than my other ones. these are a bit larger than my Cardinal Buoys (as seen below)

they have a hollow inside pipe in them also. this is so that for once there is no glueing weights to the bottom! all you need is a bolt the size of this (see below) or larger to put inside while it is printing

any comments or questions, please let me know.

I have now designed a 2nd version and will upload the files after this, the 2nd one using a flashing light and 2 AAA batteries. I have not printed it yet though so if you make this one tell me how it works.
