Fits perfectly. Thanks a ton!

Great model with a few exceptions. I printed the slim model in my 300S and it fits and prints great. The issue is that it is very difficult to add the nuts after the print is done. Also, I don't feel the need to glue the top in place as the press-fit seal works well. In my opinion, the bottom should be sealed and part of the design to get rid of screws/nuts (and even save some filament/time). Instead, use the top as a press-seal to add and remove charcoal rather than gluing it into the bin, which is what I am doing. For anyone curious, I am using the charcoal here ( https://a.co/d/0ceivbZM ) and the slim version of this insert takes about 0.5 lb of this charcoal and doesn't seem to spill any.
