This a door wedge or door stopper. It can be made to any size that's needed. I printed it out of flexible TPE. Rubber works best. I never made it out of any other material. Print it as it is in the pics. Use honeycomb infill and no top or bottom walls. The vertical walls adds the stiffness. The more vertical walls the stiffer the part. Infill has the same affect. I printed mine with 10% infill. I printed mine in my MK3 using Priline flexible TPE.
