This candle moulds needs to be ideally done as a two part silicone mould. Due to the overhangs and the number of possible entrapment areas I would not try to do this mould as a single silicone casting. So I guess you can call this a intermediate level mould as you will have to look up how to do two part silicone mould on youtube, and there are a number of videos that can show you how.I ensure that you get the best quality with no support I have separated the 2 major components of the mould into the sides and inner cube. Print the sides 6 times and the inner cube once. Then assemble.I would recommend ABS so that you can use a wider range of glue materials other than superglue on PLA.ABS @ 245 degcBuild @ 60deg cInfill @ 15%Layer @ 0.1
