Atlas O Roller Bearing P48 Bolster

Atlas O Roller Bearing P48 Bolster 3d printed Model trains Miniatures
These are drop in conversions to narrow the width of Atlas O Roller bearing trucks to prototype width for Proto 48. I have printed these with the Black Strong and Flexible material and the parts came out just fine, so that is now the default material.
