PROJECT INFO:

I want to share a project I've been working on for several months now.

It's the overhead panel frame of a Boeing 737NG and its respective panels, in SVG and STL.

My love for aviation is longstanding, and I've been very involved with flight simulators for many years.

My first home cockpit consisted of two boxes with 10 buttons each, where I used two USB controllers as an interface to the PC, with buttons soldered directly onto the circuit board, because at the time, Arduinos and Raspberry Pis didn't exist yet.

Over the years, my cockpits have evolved, technologies have kept pace, and currently, I'm building a home cockpit based on my beloved 737-800 my 5th or 6th version. It's not a 100% faithful replica, as it's very difficult to obtain all the necessary measurements and information, but let's say it will be a 95% accurate replica.

That's where this need and this project came from. To build it, I based myself on measurements available online, videos, real photos, and some common sense and compromise. I can say that the scale is 99% accurate.

I built everything from scratch in Fusion and Inkscape.

FRAME:

In this project I will provide:

-The different STL files of the frame panels (i dont have SVG of it)

-The panels themselves in SVG and STL format

-Any other content you deem appropriate.

I remind you that this frame is designed for my panels, however, feel free to adapt them to your needs.

For some frame panels, as they are too large for my print bed (I currently use a Creality K1C), I also provide a split version of them.

All panels fit with dovetails and also have holes for M3 screws, so you can screw everything together for even more rigidity.

The dovetails on the panels have some leeway, but the joints on the split panels are tighter, so have a soft hammer nearby to help.

Regarding printing, I used these settings:

-0.20 layer hight

-3 Walls

-15% Infill giroyd

-No Brim

-PETG

The frame height is 50mm and the panels i made of 3x 3mm acrylic sheets. The frame will get M4 brass inserts with 5mm OD to fix the panels to it.

The frame panels take in average 3h to 6h to print in my printer. Of course the smaller ones (like the center, etc), take less than 3h.

I know many of you may think the design is poorly done, that you wouldn't do it this way, or question many of the decisions I made, and I believe you. I'm no Fusion wizard, I know how to get by, and for better or worse, this project is here and it's free and really works for me.

PANELS STL/SVG:

The first batch of panels in STL already avayable (1 to 6). To build each panel, you gave to make a sandwich of 3x 3mm panel. Beware because i dont 3d print test them, im only converting straight from .SVG to STL, i used a laser cutter with the .SVG files.

You will have at least 4 files for each panel, the base is where almost all the buttons will fit on, the middle is used as a spacer for the button nut and the top you have to choose between a panel with no letters or with lettering. For exemple, one approach you can take is to print he panels without letters and then, print a sticker to put on top.

The different panel layers will secure to each other with M3 screws, the panels to the frame with M4 Screws.

Also if you have a laser cutter, the .SVG's are still avaiable, but you must prepare them yourself (Select the cut lines, engraving lines, etc), since the laser cutter software may differ.

FINAL THOUGHTS:

You have the files and also the .zip files where everything is divided. If you want to work with the non path svg files, you will need the font MS 33558 (Not sure if is copyright or not, so google it).

Since im still building and printing the final pieces, i will post any updates here.

I want to share this project with you for free, but if you'd like to contribute, please feel free to do that.
