I backed Tim's KS for one of his, but I'm still going to build one or more from your BOM when I get caught up with the printers I'm making. In the BOM you didn't state what size the auger to get. I also want to make the heater band with 4 of the 12 volt, 40 watt cartridge heaters. Just want to keep all the voltage at 12 volts on the extruder board. This is where I need help on picking a PID that will work on 12 volts. I'm not very good with electronics.
I would be afraid that the plastic chips will scrape bits of the Bondo and get in the filament with your fix for the "T".
Instead of using a T on mine, I'll just mill a slot in the black pipe and make a clamp around the pipe with threads to hold the soda bottle. The clamp will be 2 pieces of 1 1/2" X 2" by 3" long alum blocks bolted together and drilled down the center where the 2 pieces of alum come together for the pipe (same as the OD of the pipe) and then drill a hole in the top for the bottle.
Keep up the good work
