After what seemed like an insane amount of trial and error, I came up with a large list of details that must be followed precisely to achieve a successful cast. The temperature on de-mold is important since it takes about 2 hours for the inner core of the wax cast to cool. If taken out prematurely, the inside is still a thick soup. If taken out too late, the wax contracts too much and cracks. However, if the mold is not separated from the tray after 45 mins, separating later will crack the model. If there are screws plugging extra holes, they have to be taken out at this time as well. There are also specific considerations for designing the silicone molds to be able to release the model successfully.

This week I also completed a "Dark" version of the assembly instructions guide. It's mostly for screen media, but I would like to create a print version next. I aways liked those thick catalogs with black pages that art schools send out, and I think this might achieve that look, if I find the right print supplier.
