Crosman 1377 Tri Picatinny Rail Remake

A triple picatinny rail adapter for the Crosman 1377 air pistol.It's a remake of this: https://www.thingiverse.com/thing:3117783 Using the original: https://www.thingiverse.com/thing:250950Note - I need an appropriately scaled Crosman 1377 CAD model. If you know where I could get one please let me know. I can't make a precision model myself and don't own a printer so I can't verify the fit or improve my modelImportant: Having received two samples printed, the rail will not fit as is. The hole for the barrel needs a bit of sanding, and the protruding end of the top rail does not smoothly fit over the plastic breech without considerable sanding. The picatinny rails are too "tall" for my accessories so those need adjustment as well. If you just sand down the outer faces of each rail your items should be able to fit, but I want them to be able to fit as printed. I can fix the rails, and I will soon, but I can't do anything about the barrel and air tank misfit until I have access to a scale CAD model.This version is more appropriately detailed and doesn't have the large file size of the other tri rail.I think the other creator used the "solidify" feature in mesh mixer and didn't simplify it after. That basically means there's more verts/faces than needed, and corners and edges are softened.I thought it'd be simple to just manually remake the model with the simpler topology by using the single rail model in blender and manually repairing it.I don't know if there are any benefits to the actual print quality or cost though. I am fairly new to this and don't have direct access to a printer.This uses slightly more material due to how I attached the side rails. The hole for the non-existent barrel is closer to the center on either side, making the section between the secondary holes and the bottom of the side rails thicker.I figured this wouldn't be a problem since it may provide some additional structural support. The V2 model has a thicker base and the holes are reshaped.
