Door Threshold Spacer (Customizable)

I needed to adjust the height of an exterior door threshold for a better seal between the vinyl threshold insert and the bottom of our door, so I created this spacer to put under the metal threshold. In our case the center of the threshold needed to be higher than the sides, and I printed 4 sections (total 31.5") that I stuck to the floor under the threshold using caulk, and then reattached the threshold to the floor.

SCAD file attached for you to customize with any dimensions that you need (attached STL is just an example).

I recommend printing with 100% infill.
