I saw this $4 wooden box in the Reject shop yesterday and thought it could be quickly adapted to a simple eyepiece case. I still need to partition off the collimator section, add a few layers of varnish and glue foam to the sides and lid but I thought I'd post a few photos to show what could be done.
By the way, the box is constructed from fairly light wood so don't expect it to offer too much protection. It isn't a big problem for me at the moment as I'm upgrading from a dew soaked shoebox
