DIY Safety and Compatibility Notice
Safety, compatibility, and responsibility information for DIY electronics and repair parts.
Last updated: July 13, 2026 · Policy version: 2026-07-13
Unassembled parts and intended user
DIY electronics kits and compatible repair parts are supplied as components or unassembled kits unless a product page expressly states otherwise. They are not toys, are not intended for children under 14, and require competent adult supervision when used by younger people.
Installation and electrical safety
You are responsible for confirming voltage, polarity, current rating, wiring, firmware, mechanical fit, and safe testing before installation. Disconnect power before servicing equipment. Batteries, mains-connected power supplies, and adapters are not included unless the product page expressly says so. Seek qualified help when you are unsure.
Compatibility and third-party brands
Compatibility depends on the exact printer, board, module, revision, and firmware. Product references to another brand or model identify compatibility only and do not claim affiliation, endorsement, or authorization unless we expressly say so. Ask before ordering when you cannot confirm the exact model.
Damage and mandatory rights
Damage caused by incorrect wiring, reverse polarity, wrong voltage, short circuit, overcurrent, overheating, soldering, modification, or improper installation is not covered by our voluntary return policy. This notice does not exclude liability or consumer protections that cannot legally be excluded.
