Trailer Wheel Chock I had a need to fill. Sure I could have bought a set but where is the fun in that? I got a warning ticket to move my 5 x 10 Utility trailer off the street in front of my house. My driveway is sloped down towards the road, I wanted to make sure it did not move. I was using a chunk of old firewood but that was before I got into 3D printing. I have included the stl and two 3mf files for Bambu studio, PETG and TPU profiles. I recommend 3 walls, 5 top/bottom and 10% triangle infill. I have printed both and both are great.The red set are PETG and the orange are TPU. I currently have the PETG set in use, want to see how they perform over the summer. I also put a paver behind the chocks for extra peace of mind. See pics. This device is not an approved safety measure in any country, state, planet or universe. Use at your own risk!
