Could you please record a simple video of this buffer working?

What is the buffer length?
I need to buffer 1551 mm and am having a hard time finding a solution.

Greetings Sir, I'm getting closer to implementing. This is where I'm at now, my current system uses the OD 4mm tubes. I was writing to you on reddit about instructions and understanding the process. I think I just need to make the lower half and figure out how to mount it on my wall. I've attached a photo of my current setup, which is a headache to use. I'm thinking about the dry box idea to throw into the mix. I think I'm on the right track, I used Prusa PETG for the filament for strength. If I'm understanding things right, I just pop the top cover up and off to load filament in to the wheels? Do I even need the 5 retaining clips, or is that overkill? Thanks for making this, anything is better than the OEM solution from Prusa! (edited)

I was nice to see you and chat about your filament buffer. It looks like a well thought out design. I don't have a need for it right now, but if in the future I get another printer with the MMU, I will be coming back to this. You have done a lot of good work and design on this.

oh, good catch
I used MR126-2RS Deep Groove Ball Bearings

6mm Inner Dia
12mm OD
4mm depth

you can source an uxcell 10 pack on Amazon. I'll update the documentation later today.

Nice design! What is the spec of the filament wheel bearings please?
