5 Tools That Make 3D Printing Easier

A pen-sized rotary tool for the finishing jobs where a full-size one is overkill: support scars, rough holes, blobs in corners. Its real advantage is size — it can stay next to the printer, so a 20-second cleanup actually takes 20 seconds instead of a trip to the tool drawer.

Pro tip Run it on the lowest speeds for PLA. Plastic softens fast under a spinning bit, and at high speed you smear the surface instead of cutting it.

The tool that turns 3D printing from guessing into measuring. You check whether your filament is really 1.75 mm, whether that calibration cube came out 20.00 or 20.30, and how much clearance a snap-fit needs before you print it five times.

Pro tip Measure filament in three or four spots along the spool, not once. If the diameter wanders more than a few hundredths of a millimeter, that’s your inconsistent extrusion — not the slicer.

A flush cutter is one of the most common tools to keep next to a printer. Supports, brims, stringy blobs and the ragged end of the filament all get one clean snip, and because the back of the jaw is flat, the cut sits flush with the part instead of leaving a little stub you have to sand off later.

Pro tip Before loading new filament, cut the tip at a steep angle. The pointed end slides past the extruder gears and into the hotend much more easily than a blunt, bent end.

Most clogs aren’t in the nozzle tip — they’re a plug of plastic stuck higher up the filament path. This is a long, stiff 1.5 mm rod with an arrow tip shaped to match the nozzle, so instead of poking a thin hole through the jam it pushes the whole plug down and out. For a lot of everyday jams, that can replace a full hotend teardown.

Pro tip Heat the hotend to printing temperature before you poke. You want to push soft plastic out, not force steel through a cold, hard plug.

A liquid bed adhesive that works with temperature instead of against it: while the bed is hot, it helps the part hold on so corners don’t lift, and once the bed cools to room temperature the part is designed to release without tools. The foam tip spreads a thin coat without spills, and one coat is good for several prints.

Pro tip Let the bed cool all the way before you take the part off. The release happens at room temperature — pull it while it’s still warm and you’re fighting the glue.
