Hi Barnabas,
Welcome to the forum 
I’ve contacted our supplier and they don’t yet have a shaft coupler that fits these mecanum wheels and is available separately. The shaft couplers that are included in the smaller-size wheels is still only a press fit adaptor to suit the ‘TT style’ plastic brushed motors so it’s not great.
I suspect a press-fit coupler will quickly loosen anyway due to the outward pulling force that a mecanum wheel will experience.
We do have some GoBilda mecanum wheels which are 96mm in diameter and way higher quality, but it’s a big jump in price.
Rather than gluing in a press-fit, plastic adaptor which is hard to source, I think you might have more success by drilling out the mecanum wheel to a size that will support a more common hub size. You’ll probably break a couple in the process but the hex shaft on those mecanum wheels is just totally unique so there’s nothing standard to suit them.
And you can get our latest projects and tips straight away by following us on:
