Light Under the Fan Casing of a 3d Printer.

The reasons for light under the fan casing of a printer carriage especially when the print is not bigger then the fan casing. I want to know what the nozzle is doing in the first layer and in real time for reasons is my bed adhesive enough or did I level my bed well. Although the 1st reason can also happen after a few layers done. An other reason is that especially with petg to much filament is extruding and it sticks to the nozzle, and you have got to pause the print to wipe it of the nozzle or begin again when you cannot lower the temperature in your 3d sliced file in real time. Or support has not been adhesive to the bed. The whole print has got to begin again. For all those reasons a nozzle in light helps a lot especially with chinese 3d printers, creality, ender3, geeetech and sofort. I 3d printed 2 parts for it, the led holder with a thrench in the middle for putting the wire and the resistor in it. The magnetholder to attach the magnet holder on the metal fan casing. I printed it in 2 parts because a big overhang would appear, when I 3d printed it in one part, and that the magnet without magnet resistance through the plastic fits well on the metal casing. I chose a resistor of 120 ohm on a max 8 volt, 2 times a 18150, this will give a very bright light. Measure the current with multimeter between batteries and resistor. 60 mill.amp is max. With such capacity one charge of a battery will last long. I include 2 .stl files the magnet holder and the led holder. They have been printed in petg, but I think you can use pla as well. You can mount the part from the corner toward the middle en in a diogonal way, both posititions will leave the holes open for letting the air of the fan out. You cannot use it with a large print as the light will travel over the clamps and there is no space for that. Use your clamps as wide as possible. When you use no glass bed but a much lower build plate, like a pei sheet or magnetic sheet, the light is just a liitle bit lower than with glass of 3mm.
