I just went to Lowes and had them cut some Glass for the Bed and use only the heated glass bed for printing. I've printed Pla and Petg staight on the glass, I just scrap it clean and wipe it done with denatured alcohol. I had some problems with lifting recently but it turns out my nozzle was to high and my bed bed wasn't level enough. Now that I got past this point all my problems are gone. As for the enclosure I have an office built into half my garage (its insulated but rely s on heat from the rest of my house via a wood burning stove and a small portable heater. I would hold off on the enclosure till you get it up and running and navigate the wire management.
