BUTTERFLY three piece bath bomb mould/mold.  I use these mould designs as they are the strongest type and the easiest type to get the bathbomb out when you are making them.  The three items come packaged in a hang sell bag with care instructions included. Finished product will be about 90mm across and the thickness will vary depending on the maker, however the ring height is about 42mm.   Home made in Townsville. All our materials are sourced from Australian suppliers. The molds/moulds are made from PLA on a 3D printer at my home in Townsville from designs sourced from all over the world. PLA, or Polylactic acid also known as poly(lactic acid) or polylactide (PLA), is a thermoplastic polyester.
