Based upon my previous design, this stock extender will add 100mm to your Nerf Retaliator, as well as a simple tactical rail. The design is now split in half and includes alignment tabs and screw holes that will fit a #4 screw.
Both versions are based upon an original design by Hobbes32.
In addition to the raw .GCODE file, I've included a few .3MF files with different positioning for supports, as well as the individial .STL files.
Print at 0.3 mm. Use a #4 screw in the hole on the side to lock the stock extender in place.
