3D Printer Dampening Feet

I was on a mission to try and find a way to both quieten my 3d printer, as well as have virtually no vibrations shaking the house and keeping everyone awake, while also not sacrificing print times and quality. I've tried dozens of different ideas and feet designs to try and reduce the amount of noise coming from my printer, but none would meet my expectations.

My design, on the other hand, significantly reduces the noise given off by the 3d printer, with now the limiting factor being the blower fans, and has also ELIMINATED vibrations, which means people won't even know that youre 3d printing overnight.

I initially tried super wide and soft conical springs, which didnt need a design to keep upright, and it worked really well, but they were just too soft, which meant in certain situations would bottom out and bang a lot, as well as if you wanted to move the printer, the springs werent attatched whichg meant that you had to realign the springs every time you moved the printer.

The springs that i chose are 2x(13-26)x40-7, which means the pring wire is 2mm, top part is 13mm, bottom is 26mm, height is 40mm, and is coiled round 7 times, this i found to be the perfect spring, where even doing 10 min benchys wouldnt come close to overloading the springs, as well as not being too stiff, (and also being quite cheap on aliexpress).

And like my other designs, I used 2mm bike spokes, which are both super easy and cheap to get hold of, as well as being super strong and rigid to keep the springs in place with the design.

Parts needed

4 x conical springs of size 2x(13-26)x40-7, easily found on aliexpress
~500mm worth of 2mm steel rod, or about 2 bike spokes, with 8 x 38mm length, and 8 x 23mm length
Your filament of choice, it can even be PLA

Instructions

1. Get the spring and locate where the spring wire ends at the bottom of the spring, and place the spring so that the end is at the opposite side of where the dot is on the top of the print
2. Get one of the pins and insert it where the dot is. You might need a small hammer to tap it in, and insert it until halfway in
3. Get pliers and slowly and carefully twist the spring counterclockwise, which will bring the end of the spring to the other hole to the left of the pin you just put in, and stop when you can't see the spring anymore when you look in the left hole. (This might take a few tries the first time round, as you might turn the spring too much and unclip the spring. Just take the pin out and start again until you get this step)
4. Insert the other pin in the other hole and push/hammer it through all the way
5. Then, lightly tug the spring with pliers clockwise this time so that the spring sits against the pin you just put in, and then afterwards insert the first pin you put in the rest of the way
6. Do that with all the other springs, and if you printed the vslot ones, insert them into the vslot channels
