>You’d think for 140 bucks, that making one of those wouldn’t be a chore?<
What he said.
Try making one yourself for $140. Good luck. Buy all the needed materials. Create the positives out of something (have fun). Make molds of the halves. Then cast them. Add the hardware. Good luck on the gel. I don’t have a clue what he uses. How many hours will all this take you? The materials alone will cost $100 or better for a one-off, plus a tremendous amount of time. And then when your first try doesn’t work out, you get to start over.
