Keter rail T-nut

Have a Keter work table and needed a better way to clamp pieces of wood to it so have remixed the Keter paint points made by projmantn (https://www.thingiverse.com/thing:3342309) to make some sort of adapters to add 1/4" bolts to the table T track to use some holdown clamps (printed this ones https://www.thingiverse.com/thing:2841271)
