I think it's because they were originally 3D printed. They take a while to print, and making $5-10 each and having to fund, what I am guessing, $500-2000 for a printer makes it hard to scale. It's not like he's making billetboxes and selling them for nearly $300. The price is simply too low.
Last I heard he was getting another version made using injection molding (in China). Makes more sense. Would cost less than a dollar per unit and could sell for 10* the cost. Could get thousands of them made per batch. I think he's selling them now but they're also way too slow getting to store.
3D nylon printing something that can be made in a mold for less than $0.05 in batches of thousands??
Yeah, that's a losing business model. Now the best he can hope for us the next batch can sell relying on the "from the original Coily company".
And forget ever getting $10 on that when widely available now that multiple knock offs are already out there.
Could try to get "innovative" by making it from polycarbonate so you can "see" through when cutting the legs to save you a step in flipping it over to look where your wire clipper should be.
Granted, that'll be knocked off with a few weeks but at least he could get some brand recognition and try to build consumer loyalty (a freebie for all the original high priced buyers maybe?) so he San get some sales out of it. But let's face it, he'll probably end up competing with the same company making them for him selling it through FT.
