Why not something like this? 
Obviously I am joking but there are so many posts here where folks show the “blast furnace” they want to use to dry filament, but it’s completely unnecessary and so totally over the top. Even Bambu’s own recommendation is you can dry filament right on the heat bed, it just takes longer so the notion of hotter is better is not necessarily a “must have” but more of a “Want to have”. Sure, an oven that goes to 11 rather than 10 might seam really beefy and one would have bragging rights and maybe it even speed things up, but spending $120 on a massive oven for drying is way overkill, considering the fact that the device becomes a brick just wasting space. This device takes up as much room as an A1.
A purpose-built dryer, like the Creality Pi or similar options, does the job just fine at a 70c at fraction of the cost. They take up barely more space than a couple of spools and let you feed directly from the dryer. Why complicate things?
But don’t take my word. If you’re amazon Prime member then buy both the oven and a purpose built dryer. You got 30 days no questions asked for full return on their dime. Then do a literal “Bake-off” between the two methods and return the one that doesn’t measure up and then you have something really juicy to share here with the community.
I did this with the Creality Pi and the Sunlu S2 which I posted a review here. Sunlu S2 VS Creality Space PI Bake-Off Review Amazon never questioned the return.
