Summary

Other remixes combined the two parts, but I get that printing them separate allows for a cleaner bezel around the Stream Deck. So instead, I opted to remove some unnecessary materials from the bezel (top part). I created a stand from scratch so that most the material is toward the bottom for better balance. In addition, I added grooves and ridges so that the two parts hold together well and don't slide around as in the original.

Printing PLA at Standard Quality (0.2mm) and 20% infill, my printer used 36 grams (bezel) and 46 grams (base). At 100% infill the base should use a bit over 108 grams if you want to add a bit more heft.

Lastly, you'll want rubber feet of some kind on the bottom so it doesn't slide around so easily. I found the feet on the original stand easy to remove with the adhesive and work well for the purpose.
