DIY Frag plug

plug 1 is first attempt and plug to is second attempt. OC stand for ocean wonder plug.
hopefully the third attempt will come out better than the first and second attempt.
there is still a few things to be done before the final plug are ready to even be market. as far as prices, yes it will be cheap than other. something around $.10 a plug wholesale and about $.18 a plug for retail.
the mold i'm i just made and using is just for testing. the final mold will have 3 different size from sm, md and lg. also will be making disk, tile, frag island and going into ceramic plug in the future.
 
very nice. what was your goal in making these? Was it to find a cheaper alternative or an easy DIY plug? Just wondering but great pictures of the process!
 
what is the diameter of the dowel part? i make custom acrylic frag racks and i could buy a bulk of them to give with the racks, but need to know the size to make the holes.

So that would be 3/4 I believe..

what is the mixture that you are using? Sand and what? They look really good by the way.
