This is a double sided nerf rail mount thingy which is used to mount a masterkey to your blaster.

This is a remix of previous design (which should be linked) and I basically just made it double sided so that you can attach a blaster underneath your main blaster. (Or on top, or wherever you want)

The mount will attach to both elite and rival rails. If you print it tight enough, you will not need the screw for the elite rails, as it will pretty much just friction fit. You will need a screw for to mount to the rival rail, I just used a random sheet metal screw I had lying around, any screw of 23 mm in length should work, as long as it is 3 mm or smaller (in diameter). I originally intended to use this for a maverick, but I ended up using a takedown just to be more ergonomic. The maverick was really solid, the takedown less so, but still solid enough to feel safe.

I would recommend printing in the orientation I have it, as that way it wont snap when you pull downward on it. Mine is holding up alright in Pla, but I would honestly reccomend printing in PETG or ABS just for peace of mind.

Printed on an ender 3 with ender Pla (+/- .003mm), 0.28 mm layer height and 50 mm/s print speed.

If you have any suggestions or corrections, please put them in the comment section.

remixed using tinkercad, so I apologize in advance for my cruddy modeling skills.

I also apologize in advance for my bad photos; hopefully the concept is simple enough for yall to grasp without to much documentation.

EDIT 3/22/23

took the thing to my first nerf war and I didn't have any issues at all. The thing took some knocks and didn't fall of, so I guess it works.
