Modular 3D Printable Mini RC Crawler Rocks

These are my Modular 3D Printable Rocks for Mini RC Rock Crawlers. I made them specifically for use with my Axial SCX30, but they'd work great for larger crawlers (such as 1/24 or 1/18 scale) if you stack enough of them together. They're roughly 60mm in diameter. 

They're designed with a hexagon shaped base so they can be positioned in each direction. This allows you to make a mini crawling course in whatever shape or design you'd like. Even better, they are stackable. You can use the supplied 15mm and 30mm riser bases to make multiple levels of rocks. Even the riser bases are stackable, so you can build them as high as you'd like. The rocks and bases are held together with simple H-shaped connectors. From my experience, the rocks, bases, and connectors are…ahem…rock solid, needing no glue. However, you can always use a drop of CA glue between the rocks and bases for permanent courses. 

I've included six rock designs, two riser bases, and the connectors. I've also created print profiles for single and multiple of each, denoted with a “x4” or “x15”.
