Compression driver 1.4" non-standard 62.5mm 4 bolt to FaitalPRO LTH142 horn adapter

thingiverse

I purchased what appears to be a clone of the FaitalPRO LTH142 horn on eBay. It has a metal plate that screws onto the horn with 4 bolt holes to secure the horn and plate assembly to a compression driver. The bolt holes are spaced 4 inches/102mm apart, which seems to be a standard size. My intended use for this was to pair it with an EV DH1A compression driver. The DH1A is nominally a 2" throat driver, but has a "snout" that can be removed, exposing a native 1.4" throat that I thought would fit the LTH142 clone. However, once the snout is removed, the 4 bolt holes on the DH1A are spaced about 62.5mm apart. I'm not sure if this is a standard size, but I wanted to try the horns anyway, so I designed this part. If you want to customize for quicker printing, you can probably trim the top off of the model and still get a part that's strong enough for any other compression driver.
