Editor's Pick: Leftover filament ends used to go straight to the trash, but now you can join them together and keep printing — one spool can go much further. It heats up to 185°C in about 3 minutes, and you can even connect same-material filaments in different colors to create gradient effects. The built-in viewing window lets you see at a glance whether the joint is aligned, so no more guessing by feel.
