Flush-fit Electrical Box Covers - Multiple Sizes

ATTENTION / SAFETY DISCLAIMER:

Since this part may come into direct contact with 230VAC electrical wiring, using standard PLA is NOT recommended.

Risks associated with PLA:

• Thermal deformation: PLA has a low softening point and may warp if the wires heat up.

• Electrical safety: Due to PLA's hygroscopic nature (absorbing moisture), there is a long-term risk of insulation failure or arcing.

Recommendation: For your safety, please use a Flame Retardant filament with a V0 rating, such as Prusament PETG V0 or similar certified materials. These filaments contain self-extinguishing additives designed for electrical applications.
