I've always admitted my mechanical design skills are rudimentary at best.  And while I love OpenSCAD as a design tool (it fits my programmer's mind), it certainly is more limited in making complex designs.  A tCam-Mini user created a very nice set of enclosures and shared their STL files (and BOM for additional hardware) in his github repo.  He designed his enclosures to accommodate tCam-Mini with an external antenna but they'll also work for the units with an internal antenna.  I definitely encourage you to check them out.  A big shout out to Harry for creating these.  Some pictures from his repo follow.
