			== Dan's Design Notes ==

			Hot end:
			* start with 36mm m6 brass heater barrel.
			* screw 0.5mm nozzle onto one end.
			* screw 2 m6 nuts on most of the way to the nozzle. leave a small gap around each nut.
			* put thermistor between nut and nozzle and tighten nut and nozzle gently until thermistor stays.
			* wrap about 1' of nichrome wire around the barrel and thermistor in the gap between the nut and nozzle. it will help hold the thermistor in place. leave 2 inches of each end of the nichrome wire sticking out.
			* use the 2nd nut to clamp the nichrome wire ends between the 2 nuts to hold it in place. there should still be about 2 inches sticking out.
			* strip the ends of the nichrome and use metal crimps to attach to thick wire.
			* cut 1" off of a 5/8" dowel.
			* drill 3/16" hole through it the long way.
			* screw the end of the barrel into the wood a bit until it's really tight.
			* fit the dowel into hole in the bottom of the feeder and screw in 2 wood screws to hold it (TODO size)

			Test results:
			* ~7.5v seemed good
			* main problem is that plastic kept coming out after i stopped pushing it in

	* Using round spacers instead if bolts to mount the hot end to the plate in the middle, similar to how the plate is mounted to the feeder. They'd need to be made out of something that can handle more heat and then we might want to replace the existing plastic spacers.		* Using round spacers instead of bolts to mount the hot end to the plate in the middle, similar to how the plate is mounted to the feeder. They'd need to be made out of something that can handle more heat and then we might want to replace the existing plastic spacers to use the same part.

	~~Instead of those plastic spacing rounds, they can use metal ones, then~~ use the same ~~diameter metal rounds for the second-level spacing as I mentioned in the paragraph above.~~

	~~It requires many different pieces of hardware and the curved cuts for the mounting bracket add build complexity if cutting by hand without necessarily adding usefulness~~.

			A simple extruder design that uses a bowden tube. This page only has some of the build instructions, although what's there looks very clear and simple.
