Thanks for the advice everyone. I had tried removing it while it was hot (1ish pm) but that wasn't ideal. I ended up letting it cool all the way off over night hoping that it would loosen enough on its own. It still wasn't budging by lifting on it directly or trying to twist. Tried some tweezers for leverage, no luck either.
Try rocking (not turning) the cap a bit to see if it will break its grip.
A couple attempts with the rocking motion broke it free finally. It took a little more force than I would've liked. I had to get a solid grip on the heater cover to prevent it from being bent in any direction too far, while simultaneously pinching the cap between by thumb and pointer finger giving it a back and forth rocking motion. After a few presses it wiggled and popped out. The surface area between where the cap and the opening of the heater cover touch appeared to have some very light scuffing where the pressure must've been.
I have my cap on, with the aroma dish sitting on top as well. The cap included with my order is flattened and the aroma dish sits plenty flat enough to not be a hazard. I noticed earlier in this thread some one had the issue of the dish not working with their included rounded cap due to it sitting too unevenly. They ended up requesting a flat cap from Elev8. Not sure if Elev8 took note of the order contents (baller mod and aroma dish) and just took the liberty of including a flat cap. They still state on the website they shouldn't be used together, but other than the weight of the dish seemingly locking the cap in tight there isn't any other issues i'm encountering. The dish takes a lot longer to heat and melt the wax as expected but it still gets there over time (hour ish with the dial at noon). Only lasting concern is the thermal fluctuations causing the cap to crack the heater housing.
