This is a gridfinity storage for AstroAI DT132A Multimeter, it fits tight I have no problem with the multimeter staying in the holder when using it.
I have made a hole for the temperature cable at the back and a holder where you can put a 5mm velcro for the cables at the side.
The multimeter is AstroAI Digital Multimeter TRMS 4000 Counts DT132A

I have included the Fusion 360 file, f3d, if you want to modify it.
