I removed the rail adapter from the grip design by cmccoll8588 and attached the functional blank Nerf rail mount from cameronlconnor (https://www.thingiverse.com/thing:2331212). I then cut off the front of the grip and extended the back to better fit the overall lines of the Nerf Crossbolt. I've found it to be a significant improvement in ergonomics over the stock blaster or the use of a vertical grip.

Overall fit is very similar to a genuine Nerf accessory; i.e., a little loose but unlikely to fall off without some extreme shaking. I suggest printing the adapter linked to above on its own if you want to test the fit without printing the whole grip.
