Post a make if you print! I would love to see it.
Uses:
- For attaching horizontal grips.
- For attaching lasers or other side accessories on a side where no side rail exists.
- For attaching multiple accessories to one rail.
- As a basic sight.
- As a riser.
- To fit two accessories in co-linear arrangement to a rail that was previously of insufficient length.
- The longer variants even work pretty well as a grip themselves.
Includes versions with iron sights down the center, should you use it on the top rail.
Includes many options including different lengths for accessories that require more length of rail to mount, as well as versions with the mounting clip more towards one end.
Use the 'Clip' file with every version.
Printing: Print vertically on its end with supports under the clip part (as shown in the images), as well as in the screw head wells (can easily be removed with pliers). For variants with the sights make sure the sights are pointing upwards (as shown in the images). For the clip, also print on its end, use a brim if necessary.
