Model I created originally as WHFB proxy unit for high elves. While especially the rock is not 100% accurate to the original or neither are the proportions, I'm quite happy how the model turned out.Enjoy!
PS.You should be able to put normal warhammer fantasy scaled rider on the saddle. Also I intend to design one myself in future so stay tuned :)
Please note: Due to the thermal expansion during printing, getting all parts fit smoothly might demand sanding. Also printing head with 100% infill and making sure all teeth are supported properly might give more detailed look.
