This first one is my hotend platform. It has 2 E3D hotends in it right now. One with the bowden, the other without. Not shown in the picture is a small nylon adapter piece that a PTC connector threads into just above the E3D heat sink input. In the next few months I will be replacing my E3D's with a custom made triple extruder. I plan on selling them over the summer, assuming nothing goes horribly wrong.
Eventually I will improve this design to be sealed and airtight for use with the Dry-Draw.
And here is my filament spool holder. I print trimmer line nylon, so I keep it in a large plastic food container for a nice airtight seal. This spinner part sits in the bottom of the container and allows the spool to spin freely. Before I made this, I would constantly get jams when the spool got stuck or something. I have had my 3lb trimmer line spool in the container for about two months now and it's still dry (nylon normal gets saturated within a few days at most). The trimmer line gets pulled out of the container through a small hole that I drilled in the side of the container. I seal the hole with a small piece of electrical tape when not in use.
