tabs are often too thick and definitely need cutters. the rear wheels are far too loose to stay on. if the middle is pressed all the way in, the gears bind. many pieces could also be printed on the frame. needs a remix badly
I verified very well and reprint... sorry but you are absolutely wrong on the weel problem, you have to reprint it follow settings, see uploaded photo.
The large wheels are loose, and assembly is a little difficult. After gluing the large wheels, it works great! I did need to add rubber bands to the big wheels for traction.
