Car Mirror extender mounting clips

Many people who have a caravan or big hanger hooked to their car use extender mirrors.These are mounted using rubber straps and plastic clips while they do hold a lot they eventually break.Thats what these clips are for they are a strong geplacement for the origional clips allowing to have spares while on the road or on vacation.I have strength tested them and they are tested practical in normal use mounting 2 mirrors strapping them thight with force they did not break. I printed them in Black PLA from R3D and once from Jupiter Series from 123-3DI always print them in 100% infill for strength with 6 walls and a straight infill.My print settings:infill 100%Straight infill pattern0.4 Nozzle with 0.2 layer heightSeam position alignedSpeed is up to 300mm for inner walls and 60mm for outer walls
