Front bumper and posts for the Yokomo YR-4 II. Obviously you will have to source the foam part or create it yourself.I made the base a little thicker than the stock part, not enough to cause fitment issues but enough to compensate for the fact it will be 3D printed. I used ASA filament for its impact resistance which works rather well. Choose your filament wisely!I printed the base flat on the plate and the posts upright with support. For strength you may want to lay the posts down with the various holes pointing straight up. Use the 'Convert to polyholes' setting on Orca slicer for best results replicating the holes accurately.
