What customers say
Customers overwhelmingly praise the StupidFish Designs foam set as an essential acoustic upgrade for the Fjell R5 keyboard. The laser-cut foam offers perfect fitment, simplifying installation.

The resulting acoustics are consistently described as deep, thocky, and solid, transforming the typing experience.

It significantly elevates the final build's feel and is highly recommended.
Know before you buy
The 2mm foam is recommended for hotswap PCBs to ensure proper clearance, while the 3mm foam is designed for solder builds to provide a tighter fit and better acoustic dampening.
Yes, the 3mm plate foam is designed to work with standard configurations. It sits between the plate and PCB to help reduce unwanted resonance and improve the overall sound profile.
The 3mm plate foam is the standard choice for most builds. The 4mm option is firmer and provides a more solid, muted typing sensation, which is ideal if you prefer a less flexible feel.
No, this set is precision-cut specifically for the geometry of the Mekanisk Fjell R5. It will not provide a proper fit for other keyboard models.
Not at all. The foam pieces are designed to be placed inside the case and between the plate and PCB without the need for adhesives or permanent alterations, making them fully reversible.
