A sleeve that the stock Cera slides into and has a slide lever that can press the stock switch might be a great solution for many.
Edit: a follow up from my last cleaning when dark sludge bubbled up after first fill after cleaning. I loaded approximately 1.5g over a few days with only light colored reclaim then black sludge. I heated and wiped sludge away until no more bubbled out, about .1g came out. I then vaped the remaining down to an almost dry ceramic and loaded a new oil. Full flavor of the new oil, I am finding this sludge bubble out to be a the easiest clean out and less wasteful then a full clean. The next step is to see how long this works before a full clean is needed, it has already kept me from 1!
