I need a 3d modeler to replicate cabinet molding

I have an Ender Pro Creality 3d printer, I am new to this. I can't find conventional molding to give my original cabinets a similar look to new ones that I added. I thought about replicating and attaching to my original for a similar appearance, then paint them all a light cream color. I want one 1/4" deep x 1.5" wide x 8.5" long straight model and one corner model with the same dimensions. The unfinished is the new, the brown is the original and the other part is similar molding, but too big. I usdd that to give idea of what I am lookin for. I appreciate your time, thank you
