I have no need of this tool changer myself nor am I selling them. But that Swapper IS the OG tool changer. Industry has been using that turret style tool changer since automatic tool changers have been a thing. So there is no new idea involved in this design, just the application.

Those turrets are dead reliable on machining centers and seemingly never wear out. At least I've never had to repair one, even on 30 year old machines. To be fair, those are made from hardened steels parts. And not the plastic of the Swapper. Still the design IS well proven on production floors across the planet.

Fun side note: If you look at the photo on their web site, the turret shows 25 slots. But you can't load 25 tools, you can only load 24. Because you always need 1 empty slot in the turret to make the first tool change. The 25th tool is already loaded in the print head.

As far speed goes, it's not like you are actually making the tool changes manually. The turret is still much faster than you and the AMS/MMU systems that are common today. Is it as fast as the Prusa XL or Snapmkaer U1? Nope. But speed matters a lot less than being dead reliable. And the Snapmaker or the Bondtech still remain unproven in that regard. The Prusa XL has been proven to be pretty damn reliable, if expensive. If you want a low cost entry, then the AMS/MMU is the proven system.

My personal opinion about the Swapper is-- a cool try, but this isn't the correct application for this design. It's too big and the tech isn't hobbyist friendly except for a tiny handful of users. And it's an added cost to the money already spent for a filament changer.
