I created this model as part of my Voron 2.4 300mm build.  It was designed to mount perpendicularly across two DIN rails in the electronics area.  It has a good bit of adjustment allowing you to align it as you like.  It is design to work with another model here on Printables that I think are the most versitile DIN clips you can use:

To use these you need to print two of the clips and two of the brackets.  I attached these using the following process to get it perfectly aligned:

1. Place heat set inserts into the DIN clips and the raised portion of the brackets (see photos)
2. Attach clips to the rail
3. Align the brackets over the clips, adjusting them to line up with the mounting holes (see photos)
4. Add the M3 bolts into the adjustable slots and but only screw them in a bit to sit below the top edge allowing you to still slide the brackets along the slides
5. Place the LDO Leviathan controller board across the two brackets and adjust each bracket to align where the controller board sits
6. Lift the controller board off the brackets carefully and tighten down the bolts in the slider channels (just tight enough to hold them steady careful not to over tighten)
7. Place the board back on the brackets and bold it down with to the brackets

I hope these are useful to someone.  I know this is a very specific use for people with the Leviathan board who choose to adjust the electronics layout but it works great to put it together in a very organized and well balanced layout.

11/3/2024 - I updated the model to increase the hole size for the heat set insert for a better fit during assembly.  I also fixed a slight misalignment in the adjustment slider (didn't effect functionality but it bugged me).  I also added the Fusion 3D file if anyone wanted it for easy editing.

Enjoy…
