SCX10iii Rock Slider

The bottom of the stock sliders suck, this is my fix. Its slapped together in tinkercad, and you need to drill your own holes. Print at 100% infill, and you'll need to mirror one for the other side. I print stuff like this in PLA+, which so far seems to be holding up to trail abuse nicely.
