This is a isolation foot to isolate from the vibration of 3D printer.
I made this for 3D printer "FlashForge Adventurer3". It may be valid for other similar 3D printer. Especially suitable for printers of about the same weight（approximately 10 kg).
There are two type of foot.
One is for fishing gut, other one is for stretchable string.
Only the size of the holes for string is different. The one for fishing gut has 1.5mm diameter holes, and the one for stretchable string has 2.5mm diameter holes.
And I adjusted the shape around the holes.
I think stretchable type has better performance than fishing gut type.
Unfortunately I haven't seen much time since I made them, so I don't know about aging.
1st version : using fishing gut
I used a 0.5 mm diameter fishing gut.
You can see the route through the fishing gut in the photo.
One thing to note is that the hole through which the gut passes should be drilled to smooth the inside surface.Otherwise, it will sound crunchy and you will be anxious.
2nd version : using a stretchable string
I used a 1.0 mm diameter stretchable string.
The route through the string is same as 1st version.
But I passed the string twice to maintain strength.
