That case is what you get off a 3D printer which is working properly, rather than something like a Creality firing on three cylinders with a hole in the exhaust.

Hi.

The 1st item is a marine VHF, and the invoice / warranty forms are in Dutch, not Danish (like Australia not Austria).
The module is an Australian made (by Sigtec) ATIS module, which is sort of a 'roger beep' transmitting the station callsign through a FSK pulse train.
This ATIS became mandatory on inland waterways in 1995 or so.
This particular module also has a killer, which detects and suppresses this rather unpleasant FSK signal on the audio output of this radio (through the white wire to the audio amp).

The soviet mains charged torch has been copied into a one hung low Chinese shaver

certainly dangerous.
