The first version was basically that, just flat. It didn't take long to see it needed venting. You could force it, but there was pretty good back pressure. Once you added venting, having it lined up correctly became relevant, so an alignment pin was needed... and so on. Doing something like this could range from a piece of heavy foil -> to what we will ultimately release (basically half the mold minus the cavity). If you're making baits for yourself it seems like a no brainier. I'll be curious if any "production" guys use it.
There are some other tricky things we have in the hopper. Just need to keep flushing out the bugs until there ready.
