Dragon egg project (wip)

WIP Project: Dragon eggs

(Note: W.I.P stands for Work In Progress. Posts tagged with WIP can be voted on here in order to encourage me to re-prioritize what to work on)

The Dragon egg project consists of trying to make a mould for wax casting cool fantasy candles. The first idea I had is of a simple candle wax egg, hence the name. 

First attempts at a dragon egg model.

First attempt at a mould

.

Mould with tabs to ease opening, holes to line up the pattern, and notch to see how the parts are oriented.

I expect the first version to have a few problems, mainly the pattern might be too detailed, and when trying to remove the candle from the mould I expect it to be stuck, I may have to print the model itself and do a latex cast of it instead of 3D print it directly. I want to 3D print and test it to be sure however, I won't know if it has failed before it has failed after all. Another problem is that it has overhangs and can't be printed in the orientation I wanted.

The next version I am working on will have arched legs stuck to a larger surface of the egg body, for strength and avoiding overhangs when 3D printing.
