I added the logo (from BakaDesigns W40k vector collection at http://bakadesign.dk/warhammer-40-000-icons/).
I also reduced the magnet holes to fit my 3x1mm magnets.
Printed at 102% to fit some slightly large D6's.
The lid was printed logo down using Curas experimental bridging settings.
Model was sanded (140 through 400 grit), stained with a deep mahogany stain and given a couple of coats of polyurethane varnish.
Glued in the felt and added a set of rubber feet.
The last image is of some templates I printed out to check the sizes of the magnet/dice holes and to use as a template to cut the felt to size.
The dice are from https://www.thediceshoponline.com/dice/12122/tdso-opaque-antique-red-7-dice-polyset
