I designed but have not yet printed a part which will hold a shelf separator under the drawer, which lights can be installed on. Right now I'm trying to decide if the lower part of the enclosure should have filament storage (hopefully more organized than the current mess), or if I should try and cram my Ender3 in there and make it a full enclosure with ventilation and all the bells and whistles.
Right now I'm not planning to post the design for the brackets or the enclosure since this enclosure project as a whole is still a work in progress, and has been a big time and money drain (and would take more of each to get it ready to post).
