Rock crawler obstacles suitable for 1:18 scale crawlers or smaller.
For the low flat models, lay flat or angle it by propping it up or attaching to something.
The rock ramp is made to fit the entire footprint of a Prusa i3 MK3 (200x250mm). It is quite challenging for a Traxxas TRX-4M 1:18 crawler but doable. You'll need a small amount of supports on the outside edges. It's a large volume inside and the top surface really needs support so use lightning infill pattern if available to save on filament. I've printed with as little as 2% gyroid infill but it causes rough spots on the top layers. The Prusa powers through but I'd recommend at least 10% infill.
