Or more recently the Powerdyne Arius (I personally skate this one).
Tidy print though. (edited)

@Frog01 cool! Did you make the tires in TPU? How's the fit for the bearings you think?
@Cson yes I did it with TPU the fit is ok but could be a little bit stronger perhaps 0,5 mm smaller Diameter for the tires
Do you use AI to write those descriptions? "Flawlessly printed structure" ... you don't know how good I am at screwing up! ;-)
@BikeCyclist busted... ;)
@Cson I see! :-D Pretty slick, but it's difficult to quickly extract the main points of the design from the text.
