Microphone kit by simonwebnet

I don't think there is a need to explain what it is.
For a visual reference on the dimensions the measure of the outer circle is 64mm.
I ordered on Aliexpress (I will put the links at the end of the description) some condenser microphone capsules (pack of 10) and I have put into activity 9 to keep the value of the capacity unchanged, but the printable parts are also valid for a single capsule of any dimension that can enter the body. Customizing the capsule holder (number 0 in the files) is very simple.
In the images you should easily understand the assembly method which is however very intuitive. Those in yellow are rubber bands (very soft) that must be adapted in length and locked (I used knots of very thin wire for electronics) so that they hold the capsule block suspended, inside the body and then the body all the way. inside the cage.
All the parts to be assembled must be glued and inside the body, a 4/5mm axis must be inserted into the 4 holes (of files 6&7) from a clip for office sheets (attach).
The holes under the base are used to house magnets (if you have metal parts to attach it to).
the preamplifier box is just as simple and the ideal is to power it with battery (minimum 3v maximum 9v), I use two lipo in series (about 7.4v are fine), but a 9V battery is also ideal and lasts a lot , if disconnected when not needed.. The small screwdriver is used to adjust the gain, in the absence of something better at hand, but once you find the right setting you don't need to change it anymore. The preamp also has a 3.5mm jack input, but it doesn't coexist well with the molded mic, so if you're using one, it's best to keep the other unplugged. the output is line level and works well when connected to the line input of a PC, for example.
I suggest to use a layer thickness of 0.12mm and for the body, if possible even less). The stl files for the body come in two versions: one classic and one with the necessary support included (I needed that). There are some stl files in function of accessory or variant, you see.
Note: in the images where you see the rubber bands, those inside the microphone body pass through the support (it is the modified version to be printed without supports) which must be removed at the end of printing.
Note2: the slicer images indicate the suggested orientation. Check when supports are needed and when not. In any case, the supports are easy to remove and of very small quantities.
For suggestions to leave and clarifications to ask, there are comments, even if I don't go there very often.
Good make and remix to whoever wants.
