RC Crawler Tire Gate Marker

This is a simple course marker for RC rock crawling. While I made these specifically for use as a gate marker for RC rock crawlers, they would probably be great for marking courses for RC drifting or other RC tracks. I'm including two versions, one that has an integrated arrow, and one with separate parts so the arrow can be printed in a different color. Update 3/24: I've added new versions with hollow bases making them more suitable for sitting on uneven surfaces. (Thanks to dafitzgerald for the idea)
