For international sourcing these look like an identical wheel profile to the JMK ride version. I know someone found theirs like this on Taobao also.
oh while searching I see these
without the nice rounded profile but it could be ground to have it. It is the correct diameter at least.
you know what my dumb ass was thinking that would work. It has no spinning axle duh. Well I’m gonna leave it here for you to see.
