This is a full fledged bracket sling for the Bug-A-Salt 2.0 gun. I am using it to hang it off the side of my fridge, as shown in the last picture. The other two loaded pictures show the two placements:
- centered, which is balanced, but doesn't hold the gun as well
- locked, which is off-center, but holds the gun tight. The bracket does not hang balanced.
This design is fully parameterized, but these dimensions seem to work really well, and fits on an Ender 3 (220mmx220m) when rotated 45 degrees on the bed. If your bed is smaller, you can adjust the br_space variable, but you'll have less stability holding the gun.
The design is in two pieces, the holder and the arm. The arm is designed to allow a strong magnet (mine is pulled from an old hard drive) to hold the bracket tightly to the top of the fridge, as shown. Tape on a clean surface would also work well. The two pieces mate with a joint, so if you have some different mounting need, feel free to design a different arm. You'll need 80mm between wall and fridge if you hang it like I did.
Alternatively, you could just hang it off a screw without printing the arm at all. Or two screws if you want to hang it unbalanced.
