About this 3D model

i like BV3D's design for the carriage ends as it added extra print space, but after almost a year of printing i just noticed (i think i broke a few months back and i thought my bed was out of alignment) that the motor end of the carriage has rather large cracks through the thin sides... i added much larger radius fillets though out to make the sides stronger and i think it looks nicer. and i also added holes for 852.5mm flange bearings for the idle end of the carriage.. thanks for the great design BV3D!! i just tweaked it
