Parametric Dovetail Filler

thingiverse

This is a parametric dovetail filler designed for your removed iron sights on firearms like the Marlin 1894 and others. To create a precise fit for your gun, download the files and open the .f3d file with Fusion. You can edit all necessary parameters to perfectly model your dovetail. The editable parameters are: width_in_barrel: This is the width of the flat bottom surface in your barrel dovetail cut, measured perpendicular to the bore axis. lower_dovetail_width: This is the actual nominal width of the dovetail at the bottom. Measure this easily from the removed sight. upper_dovetail_width: This is the width of the dovetail cut at the top, measured in line with the bore axis. Measuring it this way makes it easier if the dovetail is slightly opened up, as some are. dovetail_height: This is the height from the bottom of the dovetail to the top of the cut. barrel_diameter: Obviously, this is the barrel diameter at the point where you removed the sight. If you make this a large number, adjust it accordingly. The fillers in the pictures were both printed slightly (0.2mm) oversized at the upper_dovetail_width, then hammered into place. The extra material was simply cut off to fit perfectly.
