#3

ive heard that the hubstack oring can wear down does this mean that at some point they will just snap

At such a small size, its harder to find. But, any harware store will have o-rings. Try a big department store. I worked at a small hardware store, and i dont believe we had such a small size.

Okay, let me see…

the diameter should be 5mm for the stack, and in a CAD, you’d do half, so 2.5mm

For the width, start off w/ a 4mm length, then add a groove after that for the O-ring to sit in (Spec for O-ring isn’t needed).

After you do that, add about a .5mm length after the gap for a bit of room.

It should look like this, minus the spike:

For the O-ring specs, if you have one of them, take them to the hardware store and see if they have them.
