I needed a set of markers that I could use for teaching maneuvering exercises to prepare for the motorcycle test.

The nearest practice area is designated for learner drivers only, but there are car learners who share the space. So I needed markers that would stay in place even if a car would drive over it.

So I designed these "flat" cones and printed them in durable orange Prusament PETG

Print instructions

I printed them with a hexagonal 15% infill and no bottom layers. This allows them to have a bit better grip on the ground I used 4 top layers and I recommend at 3 or more perimeters
