I have been working on many chassis designs, but am settling on the following design. I have built both sidewinder and inline pods for this chassis. Wheel base is adjustable using a plunger type set up between the pod and the chassis plate. Adjustable rod inserts into wheel block and is then held with a retaining screw. To set the adjustment length you can CA the rod or drill and insert a screw.
Picture is an earlier version, but is a good example of why I added bored tubes to allow piano wire to be inserted in the chassis to prevent sagging.
A complete new guide Flag has been designed for a work around 3D resin strength. Guide is slotted to allow credit card plastic to be cut and glued in place to work as the guide. Guide post is a long 2.38 mm screw that sets in the guide. I will Post pictures of that as well at some time. Also on display in the picture is the 3D printed front tires with a groove to accept an o ring. This presents well on the model as it looks like a full tire but has all the benefit of a zero grip QUIET front tire
