Recently bought the Sunlu Filament Bonder... immediately hated using it without a 3rd hand to stabilize things being the unit TOO compact for its own good. So I modeled a base for the unit with a few built in perks. The primary focus was to give me more stability without needing a 3rd hand, and it exceeded that goal by a far margin. Just the weight of my hand resting on the unit means I have full manipulation of the filament ends without worrying about the unit itself moving on me.
