What a super cool design... Thanks for sharing.
One piece of advice for those struggling with the crazy overhang for the loader (like I was), particularly on printers with only 1 fan blowing from one direction... Rotate the model so that the overhang is gradually moving in the direction of the airflow from the fan. This ensures instantaneous airflow contact with the overhang. Made a heck of a difference as soon as I rotated the model on the Original Prusa MK2S.
