Here are five very useful tools and gadgets for better 3D printing:

1. Calibration Tools: Calibration tools such as a digital caliper or micrometer can help ensure that your printer is calibrated correctly, which can greatly improve the accuracy and quality of your prints. A leveling tool can also ensure the printer bed is level, critical for successful printing.
2. Filament Dryer: Moisture in filament can cause various printing issues, such as bubbles or warping. A filament dryer can help remove moisture from the filament, leading to better-quality prints.
3. Nozzle Cleaning Kit: Over time, the nozzle of a 3D printer can become clogged with debris, causing uneven extrusion or even print failures. A nozzle cleaning kit can help remove debris and restore proper function to the nozzle.
4. Build Plate Adhesion Aids: One common problem with 3D printing is that prints may detach from the build plate during printing. Build plate adhesion aids such as glue sticks, painter’s tape, or a build plate adhesive spray can help keep prints firmly attached to the build plate.
5. Enclosure: An enclosure can help regulate the temperature around the printer and prevent drafts or fluctuations that can negatively impact print quality. An enclosure can also help contain any fumes that may be released during printing, which can be important for safety and comfort.
