Yeah I love the look of that. That's some serious craftsmanship as well! I don't think I could make the beautiful wooden framing etc, but I could easily print a stand and holder for the coin/capsule, which could be encased in a proper frame. Or something like that. I once made a "floating coin stand", which I thought was pretty cool. But I'd love to be able to make something really reaaaally good looking too.
One might say black magic, sorcery or just regular maglev tech. On the bottom there's a magnet in the + position, surrounded by magnets in the - position. The magnet the coin sits on is in the - position. This then forces the magnet to "sit still in the air", or rather, pushed and pulled at the same time.
Yep, it's a white modification of this holder I made. A bit smaller, as the coin in the gif is a Norwegian 10 krone.
I would say the lid of the box might be pushed up a little by your design, but I believe it would work fine. In fact, this would be better than what I was thinking, which was a device that would go from the back of the box to the last coin and be adjustable as coins were moved in and out of the box.Your concept works, too, but I would think the dividers at the thickness shown would cut down the number of coins the box could hold, whereas my idea would allow the same number of coins as usual.
Well it could always be smaller! It becomes 1mm taller by using this. I'll print one out and see how it looks. I was also thinking about having two dividers on the edges but that would mess with the staples (if you have those). I also reduced the thickness of the dividers so they are now 0,50mm which is about 1.5mm less than the 2x2's.
So, is the base an actively controlled set of electromagnets, or are you using some sort of diamagnetic material in the support? Earnshaw's Theorem says you can't do it with just permanent magnets...
Yep, it's powered with active regulation if I understood it correctly. You can buy the bases on ebay for a decent price!
Another thing to consider is what would stop anyone with a 3D printer just printing one of these up on their own? Is there an advantage to buying yours versus printing one up myself? I'm not saying or arguing that there is or that there isn't, but it's something else to consider as 3D printers become more ubiquitous. You may even be able to sell the 3D design to people who do have printers. I've seen that in other hobbies. I'm not sure on the copyright laws around 3D printable designs, but I imagine that they would hold. The tough part is enforcing them.
Well, nothing really. Anyone could just try and copy the design and print out tons for themselves, but I don't think many people would bother to go through all the hazzle. I have actually considered throwing the STL file out on Cults3D and seeing if someone wants to buy it. I'm just unsure about what price it should be. If I sell one of these for 5$, how much should it cost to let you print infinite amounts? inf x 5$, 5$, or 10, 20, or 30 dollars? I'm just not sure how to price it as I see a lot of potential in selling it. Of course, I could sell the file with non-commercial licensing, but it's as you say: enforcing the license would be tough. I was thinking about outsourcing the production to the US, since that way I could make shipping virtually free and take a lot less time. I'd recieve an order, and I could pay someone with a 3d-printer to print and send it to an address.
You are looking at an item, which properly tooled would cost an estimated $.90 each. Amazon might be a choice as they sell a lot of coin supplies. Google other suppliers- just as they distributes others, they are your wholesale market. Do not try to be the sole retailer, let those with a following lead you to customers.
Yeah this sounds like a good idea. I'll nail down the production side of things to get a steady supply going and I'll try and get a hold of some sellers on Amazon. Any popular suppliers in the US you would recommend?
