About this 3D model

8mm & 50mm diamond tipped drill bits required to drill holes in the glass. drill the 50mm hole in the side and the 8mm hole in the centre of the bottle base. when drilling the holes it works better if the bottle is full of water to aid in keeping the glass cool and reducing the risk of it cracking. you will need some small link chain or string to thread through the bottle to hang it onto a bracket or tree branch
