Self Explanatory,  But I've made ¼" Launch lugs for my rockets.    Ive started launching rockets more and more with ¼" rods,  less whip/flexing when the bigger rockets take off.    So i made these lugs to fit various size standard body tubes perfectly.   The “front” or up end has a slight taper on the front,  the longest dimension is 30mm (just over 1").   I labeled each one with the body tube size it was designed for on the bottom of it to easily identify your desired lug if you like to print a bunch at a time so they're ready next time you need one.  (also, they allow your adhesive to bite a bit more)

Sizes:

*BT-55  (33.7mm OD)
*BT-60  (41.6mm OD)
*BT-70  (56.3mm OD)
*BT-80 (66mm OD,   So LOC Precision 2.66" tubes can use this as they are 66.8mm OD)
*3" (78.7mm OD) *Specifically the 3.1" OD LOC Precision body tubes*

On some of my medium sized rockets i will install buttons and lugs for flexibility,  cant imagine using lugs on anything larger than 3" but i could make one if someone requested it
