Myles, Between the laser cut building parts and your new 3D printer you seem to be turning out models in record time. The engine house will be definitely be the center piece of your maintenance facility. Great model. Like that air conditioning unit, the details complete the picture.
I have been looking at 3D printers, is your printer a ELGOO model US-EL-3D -016? Also have you noticed any odor associated when printing? So other printers caution users about need to operate in well ventilated area to avoid odors.
