No licence and no authorization. The survey is the publisher's own measurement of hardware they bought, and any patent or trade-dress question in your manufacturing jurisdiction is still yours to answer.
What the methods prove
Empirical teardown analysis
The unit disassembled and recorded part by part.
Everything published here is the publisher’s own measurement of a legally acquired, off-the-shelf commercial unit. Qatoto does not host manufacturer-internal documents and makes no clearance assessment of its own.
Report an IP concern about this teardown
Publisher attested on Jan 14, 2026 that the unit was lawfully obtained, that the data was gathered by measurement and standard disassembly, and that no vendor-confidential material was used.
Materials and composition
Every designation below carries how the publisher arrived at it. A material named from a datasheet or a supplier is not the same claim as one measured off this unit.
ASA, UV stabilised
Enclosure · Polymer
Read off the part's own marking
Injection moulded · Grained, UV stable

Getting it made
Qatoto lists factories by capability and certification and carries an inquiry to them. Nothing here is a quote, and a factory will ask for your own files.
