Please let me know if I'm in the wrong section. So I was able to create a pretty good 3D model of what I feel a canister for a Begins / TDK utility belt would look like. I added areas for these little hinges I like and a place for little magnets on the lid and in the back, so it will stick to the belt. Shapeways was able to print it and they did a good job! BUT: I have no idea how I would make a mold for this thing and cast it. The problem isn't making a mold, I know how to do that. The problem is that there is a pretty good sized recess in this thing that I'm not sure I'd be able to get the mold out of, and I'm not sure how future casts would work with it. I have a feeling that I won't be able to pull this off of the mold if I just try it without knowing how first. I know there are a couple of members who have made canisters before but I'm just not sure how to do this one. I do want to maintain the functionality of having a canister that I can actually put something in. Any tips/tricks would be very helpful. Thanks!
