Chassis for MWS Nano Biscotte

[baldthumbtack]

I've been searching for a while and haven't found anything definitive yet--

I'm looking for a chassis, if any pre-built/3D printed ones exist, that will secure a pre-wired MWS NBv3. The challenge here is that because of the pre-wired connection, the card will have to be fairly recessed into the chassis due to a hilt innter diameter restriction of 1.125". Worst case, I'll just have to build one, but I wondered if anyone else had run across a similar scenario and might have a recommendation. Much appreciated. EDIT: It would also need to house a single 18650 cell.
