I hadn't seen anyone try this for eliminating vibration. Works great for bed-slinger designs.

(NOTE This is specific to the Creality Ender 3 v3 SE style bottom plate and OEM feet. may require modification to top-half pieces for other printers)
This design features a rigid top and bottom half of each foot separated by a buffer cast in silicone.
I tried a lot of different materials for the "spring" piece and i couldn't get anything 3d printable to work well, so i opted to buy 2 part platinum silcone rubber mix and i 3d printed the mold to cast from.

Each foot also uses 4x 30mm m4 countershrunk bolts to assemble the feet. LINK: https://www.amazon.com/dp/B0F1YPY9SN?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_3&th=1
This is designed based on the same concept that is used in sound-proofing walls in a home or building of some type. The vibration needs a solid medium to travel reliably through the feet. We deny the vibration exactly that with this design.
Made all of the rigid parts as well as the mold in PETG, but anything will work if you print it with enough infill. I used 35%
For the spring, mix the parts 1:1 and mix thoroughly, pour slowly into the mold to minimize any air bubbles in the casting. squeezing the mold and rotating it helps. It will come out pretty floppy but will become firm over time if you mixed correctly. The bolts can be screwed into the mold to create clearance for them in the final casting or you can use toothpicks or anything i guess.
Mesh files not necessarily in the ideal orientation for your printing purposes.
