Still waiting on some parts to arrive.

I have started work on the rear rim and tire setup.

The rear rim will be mounted to the rear axle using a collar and 2 long set screws. The rim will be 3D printed and then the collar will be inserted from the back side and the long set screws will lock the collar to the rim.

Below are a few images of my rear rim and tire design.




TPU tire, PETG rim and the collar with two long set screws.

Wheel collars mounted in the PETG rims.

TPU tires pushed onto the rims.


Rear rim and tire set mount on the axle.



Checking the fit of the rear axle rim and tires. Still waiting on rear axle bearings to arrive.


It just looks like the gear in hitting the lock nut.


Here you can see the collars I am using to locate the rear axle while I wait on flanged axle bearings to arrive.


I do have a rolling chassis at this point.

More details coming soon.
