Nice looking and well working Anti Vibration Feet for the Prusa Mini Base. I went for the already existing remixes first, but wasn't happy with the result, so I iterated through several designs until I came up with this one, which reduces the noise the most and works in every direction. It is a good combination of damping and bouncing to keep the printer in a stable condition. I attached rubber at the bottom (20x20mm) which reduces the noise even more and adds anti slipping. Both parts snap into each other, no glue needed. The rear right foot is 50% stronger, because it has to carry more weight. The printer is pretty much leveled. If you like to improve the leveling, you can replace the inner part of the rear right feet with the thinner design, but its only a minor change. 

Summary:

• no support
• 0.4mm nozzle recommended
• layer height of your choice
• standard slicer settings
• PETG recommended and tested
• 3x 0.8mm strength and 1x 1.2mm
• good damping and bouncing characteristics
• 20x20mm surface each

If you got any questions, suggestions or wishes I'm happy to help :)
