Summary

It's pretty loose but it should work. (Now tested V1 is trash it does work but it's terrible)

I don't take credit for this I just shortened it.

V2 I increased the slot thickness to 5mm for phat 3g/LTE/5g cards slot width reduced from 34mm to 30.25mm

V3 slot thickness is 3mm and width same as V2. V3 is designed for modern MPCIe wifi cards that don't (usually) come thicker than 3mm

The SSD holder is for standard width M.2 SSDs the MPCIe holder will fit 30mm extended width M.2 SSDs
