WORK in PROGRESSThis bumper should save your front axles (especial the expensiv aluminium stub axle[working on a 3d model of them, too]) from breaking and your wallet from buying expensive replacment parts..The bumper should not break, if you drive slow or "normal" against things.But if you drive nearly full speed against a wall the bumper will simple break because of the enormous energy (and hopefully take all the energy with it). So you should not print  just one of this. changelog:0.5.0- made the hole design stronger- longer middle holder --> "2layer bumper" - added holes for the screws0.4.1- corrected positioning of the holes
