Scalextric DPR Compatible Chassis for SCX NASCAR Aero (Monte Carlo)

thingiverse

A good friend switched from SCX Digital slot cars to Scalextric Digital, but had a large collection of SCX NASCAR cars, including several that he customized the livery on. He didn't want to give up using those bodies, but converting an SCX Digital chassis to plain analog or Scalextric Digital isn't as straightforward as for other brands. I offered to help, and this is the result. Note that the purpose of this chassis is to use AS MANY ORIGINAL PARTS AS POSSIBLE, so that the parts from the SCX chassis can simply be moved over to this new one. The only thing needed is a standard analog type guide, the wiring loom for DPR chips, and the DPR chip itself. The motor pod from the SCXD chassis can just be popped out of the old one, and popped into the new one. The front wheels can be easily moved as well, using the stub axles clipped to the original chassis. Due to the way the front wheels have struts, there is not enough room for the full DPR chip hatch. As such, the best way to install the chip is by clipping the plastic legs that hold the chip to the DPR hatch, and install it as shown in the photos. I used some thick double stick foam tape to hold the chip to the chassis and raise it up enough that the LED does not stick out too far. The LED should be flush, or very slightly protruding through the bottom of the chassis. It should never be able to touch the track. While this chassis was measured from, and tested on, the Monte Carlo model, I'm told that all Aero chassis are the same, so this should work under any SCX NASCAR Aero style body. A clean print should not require any modifications to work, but there may need to be some trimming of the chassis or body for optimum fitment, particularly the guide holder, depending on the guide you choose. Also, the chassis limiting tabs on the sides of the body may need to be trimmed down a small amount, as will the post in the center of the interior tray. See Photos. Supports are needed for some areas, but the screw holes/posts are designed not to need support on the inside. If you use PrusaSlicer, definitely make use of the pre-supported 3MF files I've uploaded.
