thingiverse

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. Dog's and Wheel Chair Story here: http://3dprint.com/18651/3d-printed-dog-wheelchair/ Instructions Big Wheel - Printed with PLA. Insert a GLCODE @pause instruction before the first layer of the top of the axis so you can put the ball bearing in place and let the printer finish printing the wheel with the ball bearing inside it. After putting the ball bering in place, put the extra ring printed on the first layer on top of it so the subsequent layer sticks more easily. Example: for a 0,3mm layer, at the end of the layer 37 add: G1 X0 Y0 @pause this will move nozzle away and pause the printer so you can insert the ball bearing. An alert will show in Repetier with a button to "continue printing". Tire - Printed with Flexible Filament but you can just use hight tension rubber tape around the wheel. Can use bicycle training wheels instead of big wheel like in the picture. Will include Instructions for the Fabric Bed soon. 1 meter of Velcro to fix the chair on the Dog using the "Velcro Holder" Part. (See Last Photo). Chest and Top Velcro. Threaded Rod Diameter: 8mm + 14 nuts. 2 Bell Bearings External Diameter: 26mm.
