Figured would throw this out there as found it useful. Hopefully someone else will too :)

FH-2 (48mm) is a little too deep for an Intellijel Palette case (45.5mm), so I used a 3D printed riser that a kind internet user designed and made available for free. It cost about €4 to print (I found a hobbiest who would 3D print small items at low cost on my local buy & sell site - Craigslist / Gumtree equivalent). Works great and no HP lost. There’s a screw on the left hand side of the case that prevents mounting it there, but otherwise is a perfect fit.
