Ericksmask, did you hand mold that chest piece or mold it into the gladiator armor? I need to order some transparent worbla. This is the one part of the costume that looks nightmareish.
I highly recommend casting the castle nuts. When you do it, Imbed a short bolt in each one (As it's casting, just hold one in place) so you can just bolt them into the cod piece. That way they will be super light weight and won't come out.
I'm actually working on the ceremonial belt. Originally I just planned on making this as a piece of wall art. But now I'm building the whole costume for Dragoncon.
There are a few pictures of what I'm working on. I just got a 3d printer (Lulzbot Mini) and I've been sculpting and printing badges (Grinder, Athletic and 500 ones) done already. Plus I worked out a good way to 3d print chain links for his ceremonial belt. They take about 9 to 15 minutes per link set.
The smaller chain links still require a bit of glue, but the larger ones for the middle chain I'm able to assemble without any glue. They snap into place.
Also, as you can see I've made some camshaft holders that hold the chain links in place. Those are 4 part each. Those are the version 1s, I'm printing a new version that will make attaching to the chain links easier.
In addition I've been printing out large links with a flat back so that they can be easily riveted into the leather leggings. Might do a very similar version for the boot links.
If there is interest I can send along the .blend files or the .stl files for all of these. I can put up a dropbox link and keep it updated with my progress.
