Hi PP i am posting here my project, i am willing to modify one of my prusa mini to direct drive extruder and more sturdy frame like Bear.
If you want the Haribo version check it here:
https://www.prusaprinters.org/prints/36631-prusa-mini-mk3s-smokistyle-upgrade-haribo
Soon i will post also all the files list of extra material and the pictures of the printer afterwards.
Please note that for using dual-z i will split the z axis connector, i will not change the firmware, also if you did notice the x axis and the extruder are mirrored because we want that minda hits those points during the calibration.
Our farm is getting bigger so we are looking for a workhorse like mk3s, so we will use all our minis to modify them.
Original Prusa MINI is a great printer as it comes from Prusa but we will give it a try, this is how we do learn stuff. :D

Edit3: Stls Uploaded for the frame, need to modify the extruder body a bit that Minda Hits as in the MINI. Also this part is not Modified take it as it is : https://github.com/gregsaun/bear_extruder_and_x_axis/blob/master/printed_parts/stl/common_to_all_versions/x_end_idler_tensioner.stl
