Samsun S25 Ultra modular case  easy to change RAM/MAG safe/ Can am magnetic  

For mag safe base, it is easy to add quad lock receiver or something similar if need in slicer.

I havent tested MAG safe base how it charges I dont have ring metal to add it in. 

Can Am magnetic base I just cut some 1mm thick metal plate in it.

Case should printed tpu, modular parts whatever you want.

Modular parts have 1mm groove what should go inside case frame. So it keeps part in case.
