This is an extension for the MetalFish S3 case, ready-made models for increasing from the board side by 10 and 20mm, MetalFish_S3_ext_BASE.stl without ornamentation.

MetalFish_S3_ext_BASE.f3d 10mm source for your customizations.

Printed from PLA plastic, because tests showed that the case does not heat up above 46 degrees.
Support is needed.

If expansion from the GPU side is required, then it is enough to mirror the model.

I printed 20mm in the photo for more efficient CPU cooling.

UPD: add light version V2. It requires less plastic

UPD: add EXTENDER 40mm - MetalFish_S3_ext_40mm with pad mount at extener.
And add power button cap Button_S3
MetalFish_S3_ext_40mm need 6 screw-nut M3 for mount stock panel and pad(for pad use M3-10 screw).
For mount panel to up case use case screw, for down i am use M4-8mm screw and nut.
