left lid 80 and 60mm fan for Ender 3 universal rear electronics case by TT

Updated.. - see below As others have said, anyone can create a remix - huge kudos to Michael for designing an amazing case. After assembling the twin cases at the back, I quickly realized that the airflow wouldn't work in my setup since without dampers under the printer, the fan at the bottom blows directly against the desk underneath. Then, a small fan needs to run fast to move some air and fast means loud. I tried several remixes of right lid 80mm fans but couldn't make any of them fit. So I created this variant. I installed an 8010 fan outside, blowing in which I powered with a buck converter. For the Raspberry Pi (which has a temperature sensor available to check), the difference is dramatic - 50+°C without and 30+ with the fan running. I found no information about a temperature sensor on the SKR Mini E3 V1.2 and will try to measure the steppers with thermistors next. This project is still work in progress... I imported the all_in_one_ender_3_case_-_left_lid.stl into FreeCAD and cut out five circles from the lid since I couldn't find a way to open and edit .stp files properly on Linux. I did variants of this with 40 and 60 mm fans on the right lid at https://www.thingiverse.com/thing:3936700 and now, as per user request, added a 60mm version for the left lid as well.
