50Products in Japan has been producing drives like this for a few years, it appears that this BJCraft Drive closely resembles these drives, but scaled up for 10s

I have a 50Products Drive for a Fantasista 70, along with the laser cut plywood mount for it. I was lucky enough to get it from a Japan (50Products won’t export)

Nice to see so many motor/drive options coming out lately.
