I wish to print J2 Arm Cover Spacer (upper and lower), i notice there is tube beside reserved for for wiring. It seems big enough and need additional support. I tried add support (Using Cura), seems use lot of filament and big support created. I foreseen after complete the printing the support will stuck inside and hard to remove from hole. Can I know what configuration you use to print the support the tube (or no print support)?
