is this 6mm gap , if so i can fit them around my printer only problem i have its double thick in front so i will have to think on getting 12mm gap feet

LOL!!! Disregard my message as i just opened Rar and ther eis a double version

Thank you i will print and test Thank you for sharing

You're welcome.

These work great, except for the glue on the Sorbothane bumpers, which by default is trash and my printer had no problem walking the rubber off the feet with just vibration.

But...I figured something odd out that seems to have solved it. Once the bumpers came off I noticed that a thin plastic film sheet was left behind stuck to the printed feet. The glue didn't fail between the feet and the bumper...it failed between this film sheet and the bumper! The bumper was still sticky so I peeled off the film sheet from the printed feet and stuck the bumpers back on. They're much more secure now.

It seems like the 3M tape that Sorbothane uses has protective backing on both sides...but Sorbothane didn't realize this and so tried to glue the backing to the bumpers...which, since it's designed to be removed during part assembly, quickly removes itself in use.

That is odd. The ones on my printers have been solid for more than a year.

These are great! thanks!

These greatly reduced the noise level of my 12" I3v. Thank you very much for sharing them.

These things make an amazing difference! I can barely hear the printer now while sitting near it. Thank you.

You're welcome. I'm glad you're enjoying them.

clough42, thanks so much for this upgrade kit design. As a testament to it's functionality and quality, with my first print with these feet installed, from another room, I was sure the printer didn't start printing yet and was still warming up. I opened the door and to my surprise the printer was already printing! Cheers!

Sorbothane is amazing stuff. If you get the right amount, compression and geometry, it's pure magic. I'm glad it's working for you.

thank you for posting the solidworks file too. That made it quick an easy to modify it for a 1.25 isolator. Keep up the makerfarm mods! :)

Noticed that you made plastic version of the z motor mounts, any chance you can upload those files and any of the other motor mount brackets you have designed up?

The motor mounts on my printer are the original MakerFarm laser-cut wood parts. I gave them a couple of coats of black lacquer before assembly.

Does the i3V not have any double-thickness wood anywhere like on the i3? I'd like to use these feet, but I still have the i3, and the front and back wood pieces at the bottom are double-thickness.

I just uploaded a version of the foot for the double-thickness locations on the i3. It doesn't have as much material, so it won't clip as securely to the frame, but it also has a wider base, so it should be stable enough. Enjoy.

The i3v doesn't have the doubled front and back frame plates. Let me see how much material is left if I allow enough space for the doubled plate.
