Fix for Marble Escape

This is an updated part for the original Bambu Labs Marble Run 003. It is only needed to be used if you printed the Marble Escape ladder from MPlusM which you can find here. https://makerworld.com/en/models/1186790-marble-run-003-jump-ramp-escape-addon-v2#profileId-1197890 I have printed 3 of the Marble runs for my kids and installed the Marble Escape V2. What happens is occasionally the marble may hit the under side of this section. It all depends on how your prints turned out and how well the assembly went together. It does not happen all the time. I cut a notch in the underside of this model to allow ample room for the marbles to go under and continue without getting stuck.Bambu Lab A1PLA.20 nozzle2 walls15% infill.36 Z distance on top of support.
