I wanted to raise my Ender 3 V2 to fit the 25mm height fans for the mainboard & PSU. In the way, why not, added it some vibration absorption too.

I used the "spring" from sirxaph, but also mixed it with another ideas:

• taller from fug99 monsterFeets
• use the original rubber feets from FONSWERKS risers

The result is a nice Arc-like riser with real vibration absorption, easy print and super easy installation/removal.

Also designed some pads for it that are mean to be printed with flex materials.

• Feet instructions:

None really, they are very easy to print.

• Pads instructions:

The settings depends on your nozzle, but the target it's to get a soft spot in the center so, no infill i'ts recommended. Just use a drop of any glue to prevent then from falling when they are not pressed upon a surface. Printed mine on TPU and worked great.
