In this video I share the modifications made to my Prusa Mini+ and i3 MK3S+ to improve first layer adhesion - especially for larger or multiple models which span the entire print bed. This is based on already existing mesh levelling mods which I've linked to below. This along with the squaring calibration were essential for the mini - and highly desirably for the i3. I also make alterations to these mods - using shim washers instead of silicone for the mini, and testing helicoil style thread repair inserts for the mini to mimic the process of the i3. Hope this provides some guidance for anyone attempted to modify their machines and improve their prints.
