Boyce Conformal Launch Lug Bulk Pack (3/16" for BT-60) spo-disabled The Estes 1/2A3-4T engine isThis is the first of a new line of bulk pack 3D printed conformal launch lugs. We needed a way to use up our partial almost finished rolls of filament and decided that everyone could use extra launch lugs so we designed these. Our bulk packs will each include 40 assorted lengths of 3 16th inch launch lugs (1 8th inch and 1 4 inch coming soon) that are specifically designed for a specific tube size so their bases can be conformal to the tube diameter.
