With the Chakra candle mould series these models should be printed in ABS plastic. This is my recommended my preference because of the ease at which the model can be sealed and smoothed using acetone once printed thus giving you a superior finish. The models should be assembled with the designs facing inwards and the edges sealed temporarily with some form of tape such as masking tape to allow you to fill with the material you are moulding e.g. Wax, cement, and resins.Silicone rubber mould.If you prefer you can Print 2 x bases and the 4 walls, then assemble them with pattern outwards so that you can cast the module as a silicone mould. You will have to do some work to remove the built in flashing we design in with been originally for inward facing moulds. If you are going to do it this way then I suggest using acetone to glue the parts and seal the joints permanently before you submerse in silicone rubber.Print settings:Extruder @ 245 deg cBed @ 60 deg cLayer height @ 0.2mmInfill @ 15%Print speed @30mm/sec
