3D Printed candlestick project

I designed this candlestick in SketchUP and my 3D printer is printing part of the mould as I type. The candlestick is designed to fit 50mm diameter candles. When all the parts are printed I will cast cast candlesticks in Herculite, an extra strong plaster of Paris.

I’m using NintaTak Cheetah flexible filament, and I’m proceeding carefully because this stuff is seriously expensive at 4x the price of ordinary PLA. Each of the three parts of the mould take 4 to 5 hours to print. As the printer is in my living room, I’m printing one piece a day so I have some quiet in the afternoon & evening.

This picture shows two of the three parts of the mould. The casting is made upside down.
