The air gun holder can be optionally glued together with the control module. Each part has slots on the bottom for the 8x2 mm magnets, for mounting to magnetic surfaces. Also the hot air gun holder has extra slot for a 8x2 magnet to trigger the reed switch inside the gun, so it will cool down and switch off as soon as it is placed inside the holder; there's also the M10x4.5 screw to hold this magnet.

The number of bottom layers should be set to the value big enough to ensure the bottom thickness at least 1 mm.
