Thanks to @Think3dPrint3d I now have an extruder block with pressure connectors in and out, my cakebox container can keep the filament moisture free no matter what the weather is doing. The spool spins fine sat on top of silica packs but will get a skateboard bearing and load cell based mount soon.
Can you provide a link to that design?

I’m pretty excited by the load cell. Keep us updated.
The load cell, spare Mega and RAMPS arrived yesterday. Now I just need an amp chip and some code. And time.
