I wanted a more secure snack holder. The bags and bowels kept sliding off our shelves while driving and I figured  I had some Ramball mounts from the Ultrashelf I designed so…. what the hay. This is a ram ball mount that tightly fits a MSR nesting camping bowl we have in our van..

The bottom hole is threaded for an M10 Knurled thumb screw. The threads didn't print for me because of the orientation I printed in. From what I have read you have to print with the bolt threads parallel to the print plate to get them to turn out (that print would require printing a ton of supports). I got lazy and dropped a M8 threaded insert into the hole seen in the picture rather than reprint the ABS part.  The tolerances for the sliding mechanism are pretty tight and will require you cleaning up the print with a bit of sanding.
