Hi!

This is a custom LARP prop I designed. 

It splits into four parts, and can be put together using magnets.
One part contains a powerbank, the individual parts can connect via magnetic phone charger connectors.
Installing RGB LED strips in each part allows the sculpt to light up, making the Yggdrasil sigil look cool.

*materials used will be linked below*

In the files you'll find:

1. Chassis frames
   1. Frame with stone texture sides and magnet holes (buggy)
   2. Smooth frame without magnet holes
2. Connector plugs
   1. Blank plug
   2. USB-C breakout board holder style 1
   3. USB-C breakout board holder style 2
   4. Magnetic USB cable holder
3. Covers
   1. Blank template
   2. Yggdrasil sigil
4. Cover frame for screwholes
    

Here's what you wanna do.

1:

Print the chassis frames. 
The stone ones are a little too thin to hold the magnets properly, and the walls break easily.
You can use 3x8mm circular magnets for the holes, but I'd recommend using a 10x20x2mm style instead. Naturally, you'll have to edit the holes in that case.
 

If you want to make your own version, you'll have to make your own magnet holes anyhow. The smooth frame has no such features pre-modelled.

The round cuts in the frame were to install the USB powerbank to supply my LEDs.

Additionally, you'll need to install three M3 heat inserts in the top holes.
The three standoffs in the bottom are intended for mounting purposes.

2:

The blank connector is simply a 15x10x10mm block.

I've used two different types of USB breakout boards, so theres two holders for them.
I highly recomment type 1!

The cable holder socket should fit most magnetic USB connectors on the market as long as they are straight. I've added a tap to strap things down with a ziptie.

The blocks can be installed by screwing an M3 screw into the little nook on the top. That should also clamp down your boards and plugs.

3:

The cover is designed to be 0.6mm thick. This allows light to shine through, as long as you're using a light filament.
The Yggdrasil logo was simply added onto the template. Implementing a layer change after layer 3 will give the lid a neat look.

The Yggdrasil version is unfortunately kinda messy. It prints okay, and has survived some rough handling, but you will have some artifacts and falling off bits.

4:

The covers were added to hide the screws of the lid. Simply squeeze in your 3x8mm circle magnets.

Electrical assembly

Honestly, this comes down to your own needs. A cheap RGB strip with IR remote was enough for me. You'll have to boost your 5V to 12, but it works. Definitely ready for more intricate circuits though!

You'll probably notice some jank here and there, but I still hope you can make something fun with this!
And keep in mind to always check the polarity of your magnets!
