Wisepro Filament Buffer Upgraded Top Cover (FB-1)

I made this to stop the bearings coming out on the Wisepro Filament Buffer. They will be releasing a new version soon so hopefully not many people will need to download this, but if you have the original version (FB-1), this is a must.

The part that covers the bearings should slightly touch the top part of the buffer, so it doesn't put unnecessary pressure on the bearings.

I have made two versions, one with letters to indicate the primary (A) input and backup (B) input, if you have the memory of a goldfish like me and need to be reminded every time you use the thing. Otherwise you can just use the unlabelled version. 

I have been using this for a few weeks now with no issues, the bearings have stayed nicely in place, but let me know if you have any problems. 

Print it with the top part with the letters facing down, no supports needed.
