After i finished building a lack enclosure for my mini+, I found that the door section was sinking, so i made this rod with screw on holders to prop the legs open and avoid the doors from crossing. 

There are 3 files for the rod: End 1 (peg); End 2 (hole); and middle rod (both peg and hole) to allow a construction of a rod. There is also a file for the rod holders, which can be screwed in with m5 screws.

These are made to be printable on the mini+.
