SpoolMount

This is a remix of a spool mount that i saw somewhere but i wanted to reduce the number of holes in the box as more holes means less effectiveness of air reduction.

So rather than making a hole for the hygrometer i decided to build on the original spool mount and have it on the inside against the plastic cereal container. The only hole needed is for the ptfe to pass through.

This has been design for the cereal box which can be found on ebay here:

You will also need the hygrometer which can be sourced here:

No screws required for the spool mount
