Nerf Polaroid Cube Rail Mount

In response to a challenge in the Nerf Group https://www.thingiverse.com/groups/nerf
this is a mount for a Polaroid Cube (with no case) to mount on a Nerf 'tactical' rail.

It was requested for the Nerf Rival - as I have neither the camera, nor the Rival, it is a remix which 'hopefully' should serve the required purpose.

Print, share, give feedback and, most importantly - let me know if it fits!!!
