About this 3D model
I haven's seen a similar toy around so I started a Fusion 360 practice project. This roller is inspired by Bomag machine which was on duty in our street while road renovation took place. I make it somehow DUPLO compatible but mainly for using their figures as a driver. Otherwise, I guess is sized too big. It makes a good companion to https://www.thingiverse.com/thing:537153 I added .step file, remixes welcome, makes also.
