Adjustable Wheel Chair for Dog (Branco Project)

Can be adjusted for different sizes by screwing/unscrewing the parts and once adjusted just cut the endless screw tips and its done. Might need soldering of the endless screw to the bolts to improve strength.
Can be used with bicycle training wheels or with big printed Wheel. See pictures.
