Replacement caps for rotary knobs

[Tom]

I've finally picked up my wheel again but sadly some of the caps fell off my rotary knobs. Now, I have no clue where they are since my wheel has been in a friends basement for three years and not been touched.

I'd like to purchase replacements but have no clue where to find them or even what brand I used back then. Does one of you guys have any idea? Thanks!

Ebay has tons of caps for rotary encoders. Which ones you need depends on the encoder, I've not seen this one before. What wheel is it? And can you post a picture of the encoder?

I've actually found a different solution: one of my colleagues has a 3D scanner. Another one has a 3D printer. Match made in heaven.

Which 3d scanner he used? I mean different scanners have different accuracy. I've only seen Space Spider gave good result, but it's too expensive, I'm looking for something cheaper for myself.

We didn't give it a go yet, so no clue so far, sorry. It's not an expensive one, so our mileage may vary.
