Here is a Lets Split Case. It is confirmed to fit the Let's Split Eh and Let's Split V2. Otherwise it hasn't been tested with other variants.

The case requires m3 heat inserts from here: https://www.mcmaster.com/94180A331

And uses m3x16 screws.

The top portion is printed face down for bed texture, and the bottom portion is printed bottom down for no supports needed.

The files are for the left half only, so just mirror the parts in the slicer to get the right hand side.
