Wheel Chock, with grippers

thingiverse

Wheel Chock! Profile is fitted to 15" tires, but certainly works with all tire sizes. The "grippers" should be printed out of TPU or similar flexible material. Scale the width to whatever size you want, but 125 mm works well for me. I drew the slots for the grippers assuming it would be printed with 0.4mm nozzle, but printing with a 0.5mm nozzle seems to work well too, with a bonus of printing faster. Print 12 of the grippers at the same time to get them all done at once. They may require a little trimming to remove the spread on the first layer. Sharp, small hobby scissors worked well for this.
