Hi, you want to use Cura? Please use the 'AI3M_ABS_PSUCover_Noctua_60x25.3mf' config file from the archive - open it as a project in Cura 3.6.0 - all settings are done automatic (incl. support blocker !!).
The trick is to set the 'skirt line count' to 3 and 'skirt distance' to 4 (under 'Build plate adhesion').
