Hi @zackattack456, feel free to scroll down at the bottom of this page and fill in your email address. As @3dprintingguy pointed out, we are working with Thingiverse on a way for you guys to feature a 3D print this button on your designs. As soon we’ll have more news on this, we’ll let you know. Cheers

thanks for letting me know
