Dometic Heki 3 Mounting Brackets (Various Sizes)

The mounting brackets that shipped have “feet” that are too short for my install, and I needed slightly longer ones that don't exist.

The 30mm x 30mm version is the same size as the original bracket.  The other versions are taller and/or wider.  Just FYI, If you go above 35mm wide it interferes with the edge of the internal Heki frame.  This was a non-issue for me, but probably isn't for most people.

I printed mine out of PC for strength and high glass transition temp, with 30% triangular infill, and they are plenty strong.  Would not print out of PLA.  PETG would probably be ok.

Along with the models, I included the Fusion 360 file.  If you something taller or longer, just open that file, click “Modify” > “Change Parameters”, and adjust the height or length as desired.  Then right click on “Body 1” > “Save as Mesh” to generate the STL.

Note: If you print versions taller than 30mm you'll need to get new screws.
