Halter Holder Victron MPPT Solarregler Solarcharger

HI,
I design a holder for my Victron MPPT solar charger as I like to put it under the seat of my VW California. To avoid a break in the cable I design the holder. In addition I will stick the charger to the side of the seat with some adhesive in furture, so I build in possibility to remove it on a later stage with screws.
As I will fix it in horizontalway, I added some airrelease channels on upper and down side.

In addition I used:

4x M3 screws 10mm
2x M3 screws 20mm
2x (i don't know the name ... kind of nuts) M3 x 5mm; Outer diameter 4,2mm
4x (I don't know the name ... kind of nuts) M3 x 3mm; Outer diameter 4,2mm
