Update

Added a feeder for the larger ptfe tube ends

 

A dry box made using a ikea samla storage box. It holds 4 spools and with 250g of silica gel I managed to get a humidity level of <10%

 

I used these items to assemble:

The spool holders are made from a M8 threaded rod, the bearing shrouds go on the bearings and the bearing spacers are placed between them. I used nuts on each end of each wheel cluster to keep them in place.

Pro-tip: use these to close the PTFE tubes off, from my experience it created an airtight seal.
