Home and limit switch brackets for Grunblau Platform CNC

I'm using the following for limits and homing:

#####Proximity sensors 12mm diameter (printed brackets)
- Y1 home and limit -
- Y2 home and limit -
- X home and limit -
- X limit +

#####Mechanical switches
- Z - (printed bracket)
- Z + (aluminum bracket)


I defined soft limits for all axes too but Y+ has soft limits only.

The Y brackets are printed with PETG filament (PLA might work but I think the PETG will be less likely to crack). The other brackets are PLA.
