Description

PDF

Please read:

These are the files as I used them to make my LX system replica.  

This includes raw STL files of each part as well as a bambu lab 3mf file that includes the parts pre cut into parts that fit the P1S build plate (256 x 256)

Please ensure you use supports where needed.

This model requires a 4 color multi-color printer.  I use a Bambu Lab P1S with AMS. Alternatively you could design a label to print on a 2D printer.

This also includes the list of materials, as well as some basic assembly notes and observations.

Please be advised that this is an advanced project. This is not a beginner 3d printing or electronics project. Just know that in order to make something that functioned as mine did, you will need to know soldering, how to send code to an arduino, ability to trim a pcb and much more.

I want people to make this their own. Do not feel the need to copy mine exactly. Consider this a starting point.

I'm also including sounds to set as system sounds.

Happy to answer any questions!

I used an old ASRock Deskmini PC, I would advise gutting some other random mini PC. I did not have any specific motherboard mount. Mine is held in by gravity.
